The leading self-driving car programs

Many major car manufacturers have tested the waters with self-driving car research.

Two statistics are helpful in evaluating how advanced a self-driving car program is: 

• How many miles it has driven (training data and investment to get cars on the road), and 
• Disengagement (how many times human drivers had to take over.)

In 2018, Waymo drove 1.2 million miles with 0.09 disengagements every 1,000 miles. General Motors' Cruse drove half a million miles and 0.19 disengagements per 1,000 miles.
