There are several companies that are leading the way in self-driving car technology, including Tesla, Google, and Uber. Tesla is a major player in the self-driving car space with its Autopilot system. This system uses radar, cameras, and GPS to automatically steer, change lanes, and park the car. Tesla's Autopilot system is currently available on select Tesla vehicles. Uber is another company that is working on self-driving cars. In 2016, Uber launched a pilot program in Pittsburgh, Pennsylvania, US, to test its self-driving cars. Since then, the program has expanded to other cities, including San Francisco, California, US, and Toronto, Canada. Google is also working on self-driving cars. The Google Self-Driving Car is one of the most well-known driverless cars. This car has been in development since 2009 and it has clocked over 1 million miles. Google's ultimate goal is to create a car that can drive itself without any human input.
