I was going to enter the self driving car business...
... but now I've read this line "... if you want to enter this space, and take on the likes of Waymo and BMW and Ford, you'll need deep pockets – tens of thousands of dollars per test vehicle" I'm not going to bother.
If I'd known it was going to cost me tens of thousands of dollars for a test vehicle I wouldn't have even considered this idea. I just don't have pockets that deep.
