I'm basing it on what those companies are actually doing right now in the real world. Both companies have paid drivers babysitting their "driverless" cars on real roads right now, and they will continue to test them this way, out of the hands of the public, for years, gathering data in a safe way over millions of miles driven. Because that's the way to gather data when real lives are at stake. Both companies are also adamant about having LIDAR and additional sensors in their vehicles that Tesla has decided aren't needed. Neither company has or will release a version to the public until they actually think it is safe to turn control over to the car entirely. Now compare that to Tesla - beta software and sub-par sensors that can't detect stationary objects in the road (there was a recent case where a Model S on Autopilot hit a stalled car on the freeway despite plenty of time to stop), can't detect obstacles at windshield level (there was a recent case where a Model S hit a parked trailer when summoned), and apparently have trouble distinguishing between sky and lightly colored objects in full daylight (the most recent accident). This is a company that is prioritizing technology releases ahead of human lives. Significantly lower accident rates compared to Model S Autopilot, if that wasn't obvious. In the future, you will take accidents per miles driven in autonomous mode and compare between Tesla, Google, Apple, Uber, etc. and then see which one has the lower rate. I am saying that Tesla will be the worst.
