It’s easy to add a few hundred thousand dollars of sensors to a $100 million plane. But $20k on a $40k car is too much and makes it cost prohibitive for most people. If vision alone can get you to say 1 crash in 10 million miles, that’s more than good enough to replace human drivers. If someone decides they want to go the extra mile and will pay for something rated for 1 in 20 million miles for 2x the cost, then they are free to do so.

As mentioned in this talk Tesla is taking an iterative approach and trying to make things safer for people today, not in 5 yrs from now. Maybe in a few years Tesla will see that to go from 10 million miles to 20 million miles they need 4k cameras at 60 fps, but the work they had already done would still have had a big impact. You don’t need to do things in one shot and get to the finish line.

I think we agree on these things. I wasn't trying to dispute their approach, rather explain their rationale for their current method, which is focused at actually selling product now.

Those sensors don't need to be 20K-40K, they just aren't mass produced yet. That's why I think Elon Musk will change his tune in some years when those sensors are 1/100 the cost and 10X more accurate than vision.
