Self Driving Cars: The future of transportation

Self-driving cars: The future of transportation

Self-driving cars are vehicles that can travel without human input. They use sensors, cameras, artificial intelligence, and software to perceive their surroundings, plan their routes, and control their movements. Self-driving cars have the potential to improve road safety, reduce traffic congestion, lower greenhouse gas emissions, and provide mobility and convenience to people who cannot or prefer not to drive.

However, self-driving cars also face many technical, legal, ethical, and social challenges. How can they cope with unpredictable human drivers and pedestrians? How can they handle complex situations such as bad weather, road works, or emergencies? Who is responsible if a self-driving car causes an accident or breaks the law? How can they ensure the privacy and security of the passengers and their data? How can they gain the trust and acceptance of the public and the regulators?

The development of self-driving cars has been ongoing for decades, with various experiments and trials conducted by researchers, automakers, and technology companies. The level of automation of self-driving cars can be categorized into six levels defined by SAE International, ranging from no automation (Level 0) to full automation (Level 5). As of August 2023, no system had reached the highest level, although multiple vendors are pursuing autonomy.

Some examples of self-driving car projects are:

Waymo: A subsidiary of Alphabet Inc., the parent company of Google. Waymo is considered one of the leaders in self-driving technology. It has been testing its self-driving cars since 2009 in various locations in the US. It launched Waymo One, a robotaxi service that operates in the Metro area of Phoenix, Arizona. It also offers Waymo Via, a delivery service that uses self-driving trucks and vans.

Cruise: A subsidiary of General Motors. Cruise is developing self-driving cars that aim to operate in urban environments. It has been testing its vehicles in San Francisco since 2015. It plans to launch a robotaxi service called Cruise Origin in 2023.

Tesla: A company founded by Elon Musk that produces electric vehicles and battery products. Tesla offers a feature called Autopilot, which enables its vehicles to steer, accelerate, brake, and change lanes on highways. It also offers a feature called Full Self-Driving Capability (FSD), which adds more functions such as navigating on city streets, parking, and summoning the car. However, these features are not fully autonomous and still require human supervision.

Oxbotica: A UK-based company that develops software for self-driving vehicles. Oxbotica's software can work on any vehicle type, any hardware platform, and any environment. It has been testing its technology in cars and delivery vehicles at several locations across the UK and Europe.

Self-driving cars are not only limited to passenger vehicles. They can also be applied to other modes of transportation such as buses, trains, trucks, shuttles, pods, trams, and even boats. Some examples of these are:

Navya: A French company that produces electric and autonomous shuttles and buses. Navya's vehicles can transport up to 15 passengers at speeds of up to 25 km/h (15 mph). They operate on predefined routes and use lidar, cameras, GPS, and odometry to navigate. Navya's vehicles have been deployed in various cities around the world such as Paris, Las Vegas, Singapore, and Melbourne.

EasyMile: Another French company that produces electric and autonomous shuttles. EasyMile's vehicles can transport up to 12 passengers at speeds of up to 20 km/h (12 mph). They also operate on predefined routes and use lidar, cameras, GPS, and odometry to navigate. EasyMile's vehicles have been deployed in various countries such as Japan, Germany, Norway, and Australia.

Einride: A Swedish company that develops electric and autonomous trucks. Einride's trucks are designed for freight transportation and do not have a driver's cab. They can operate autonomously or be remotely controlled by a human operator. Einride's trucks have been tested on public roads in Sweden and have delivered goods for customers such as Coca-Cola and Lidl.

Self-driving cars are expected to have a significant impact on various aspects of society and the economy. 

Some of the benefits of self-driving cars are:

Safety: Self-driving cars can potentially reduce human errors that cause most of the road accidents. They can also react faster than humans and communicate with other vehicles and infrastructure to avoid collisions.

Efficiency: Self-driving cars can optimize their routes and speeds to reduce travel time and fuel consumption. They can also coordinate with other vehicles to form platoons or convoys that reduce aerodynamic drag and traffic jams.

Accessibility: Self-driving cars can provide mobility and independence to people who cannot or prefer not to drive, such as the elderly, the disabled, the young, or the intoxicated. They can also offer more comfort and convenience to the passengers, who can use the travel time for other activities such as work, entertainment, or rest.

Sustainability: Self-driving cars can reduce greenhouse gas emissions and air pollution by using electric or hybrid engines, driving more smoothly, and sharing rides. They can also reduce the need for parking spaces and road infrastructure, freeing up land for other uses such as green spaces or housing.

Some of the challenges of self-driving cars are:

Technology: Self-driving cars rely on complex and sophisticated systems that need to be reliable, robust, and secure. They need to be able to handle various scenarios and conditions that may arise on the road, such as weather, traffic, pedestrians, animals, road works, or emergencies. They also need to be able to communicate with other vehicles and infrastructure using common standards and protocols.

Regulation: Self-driving cars need to comply with the laws and regulations of the countries and regions where they operate. These laws and regulations may vary widely and may not be fully developed or harmonized for self-driving cars. They may also need to be updated or revised to accommodate the new technology and its implications. Some of the issues that need to be addressed are licensing, testing, certification, insurance, liability, data protection, privacy, security, ethics, and social responsibility.

Acceptance: Self-driving cars need to gain the trust and acceptance of the public and the stakeholders. They need to demonstrate their safety, performance, and benefits. They also need to address the concerns and expectations of potential users, customers, partners, competitors, regulators, and society at large. They may also face resistance or opposition from some groups or individuals who may fear losing their jobs, their control, their identity, or their values.

Self-driving cars are a promising and exciting technology that could revolutionize the way we travel and live. However, they are also a complex and challenging technology that requires careful and collaborative development and deployment. They are not a panacea or a threat, but a tool that can be used for good or evil. The future of self-driving cars depends on how we design them, how we use them, and how we adapt to them.

Some of the disadvantages of self-driving cars are:

They could be very expensive to buy and maintain, especially in the initial stages of their development and deployment. They would require sophisticated sensors, software, and hardware that could cost over $100,000.

They could pose data protection and privacy issues, as they would collect and transmit large amounts of personal information about the passengers, their destinations, their preferences, and their behaviours. They could also be vulnerable to hacking, cyberattacks, or misuse by third parties.

They could reduce employment opportunities for human drivers, such as truckers, taxi drivers, delivery drivers, and others who rely on driving as their main source of income. They could also affect other sectors that depend on human drivers, such as hotels, restaurants, gas stations, and car repair shops.

They could create ethical and moral dilemmas in situations where they have to make life-or-death decisions, such as choosing between hitting a pedestrian or a cyclist or sacrificing the passengers or the occupants of another vehicle. They could also raise questions about who is responsible or liable for any accidents or damages caused by them.

They could face technical and regulatory challenges that could limit their functionality and availability. They would need to be able to handle various scenarios and conditions that may arise on the road, such as weather, traffic, pedestrians, animals, road works, or emergencies. They would also need to comply with the laws and regulations of different countries and regions, which may vary widely and may not be fully developed or harmonized for self-driving cars.

Some of the advantages of self-driving cars are:

They can improve road safety by reducing human errors that cause most of the road accidents. The United States Department of Transportation (USDOT) predicts that the rise of driverless cars will see the number of traffic deaths fall by 90%.

They can lower greenhouse gas emissions and air pollution by using electric or hybrid engines, driving more smoothly, and sharing rides. Ohio University's Future of Driving report states that harmful emissions will be reduced by 60% after the advent of autonomous vehicles.

They can provide mobility and convenience to people who cannot or prefer not to drive, such as the elderly, the disabled, the young, or the intoxicated. They can also offer more comfort and convenience to the passengers, who can use the travel time for other activities such as work, entertainment, or rest.

They can reduce traffic congestion and travel time by optimizing their routes and speeds, coordinating with other vehicles, and eliminating stop-and-go waves caused by human behaviour. The State Smart Transportation Initiative states that lane capacity could increase by 100% and traffic speeds by 20% with self-driving cars.

They can save money and resources for consumers and society by reducing fuel consumption, insurance costs, running costs, parking fees, and road infrastructure. KPMG's Connected and Autonomous Vehicles – The UK Economic Opportunity report states that UK citizens’ travel time could be reduced by 40%, saving £20bn in increased productivity.

Here is a brief overview of how self-driving cars work:

Sensors and cameras: Self-driving cars use various types of sensors and cameras to create a 3D image of the world around them. Some of the common sensors are radar, lidar, and ultrasonic sensors. Radar uses radio waves to measure distances and speeds of objects. Lidar uses laser pulses to create a high-resolution map of the environment. Ultrasonic sensors use sound waves to detect nearby obstacles and curbs. Cameras capture images and videos of the road, traffic signs, traffic lights, pedestrians, and other vehicles.

Artificial intelligence and software: Self-driving cars use advanced software and artificial intelligence to process the data collected by the sensors and cameras. The software uses machine learning algorithms to recognize objects, predict their movements, and plan the best course of action. The software also follows the rules of the road, such as speed limits, lane markings, traffic signals, and road signs. The software controls the actuators that steer, accelerate, brake, and signal the car.

GPS and inertial navigation system: Self-driving cars use a GPS unit and an inertial navigation system to determine their location and orientation. The GPS unit receives signals from satellites that provide the car's latitude, longitude, and altitude. The inertial navigation system uses accelerometers and gyroscopes to measure the car's acceleration, rotation, and direction. The GPS and inertial navigation system work together to provide accurate positioning information even when the signals are weak or blocked.

Self-driving cars are not yet fully autonomous and still require human supervision and intervention in some situations. There are different levels of automation for self-driving cars, ranging from no automation (Level 0) to full automation (Level 5). As of August 2023, no system had reached the highest level, although multiple vendors are pursuing autonomy.

Some examples of self-driving car projects are:

Waymo: A subsidiary of Alphabet Inc., the parent company of Google. Waymo is considered one of the leaders in self-driving technology.
