That whole article reeks of biased news. A large part of their "factor" is how many vehicles they could produce with self driving cars... of course Ford and GM can mass produce more cars than Tesla.. smh
To date, Tesla, with all its overhyping of autonomous driving system, hasn't produce a convincing video showing its car in fully autonomous mode navigate the streets of San Francisco through congested pedestrian crossings, road repairs, double parking unlike GM's Chevy Bolt. This really confirms that Tesla is on the 12th place. Tesla's claiming override incidents per mile are the lowest, but most of its miles are superboring freeway miles! The best fully autonomous system should handle the widest number of edge cases that aren't normally assumed.
