i have no idea why you're being downvoted. auto and avionics companies go through hell to test this stuff at a level that involves the hardware and how it integrates with the software. this just doesn't happen in most software companies.

this is much more than a software problem. i've heard of people verifying opcode behavior on avionics processors to determine the correct implementation of the hardware - when your software relies on it it's fair game.

i don't doubt that google could do this if they made it a priority. but it's a huge issue that encompasses more than a "software algorithm." if the collisions sensors degrade over time doesn't matter if the software works.
