I've said it before, and I'll say it again: Waymo's approach to self driving is a fool's errand. The only reason it works is that they have mapped out cities with straightforward roads and sunny weather to millimeter precision, and have hardcoded vehicles to operate in those conditions.

Compare this to Tesla's AI-first approach, aggregating training data from millions of drivers across the US. There's no overhead to introducing Autopilot in a new city it's never been in before--it just "works," with no expensive 3D mapping required, by extrapolating cheaply acquired vision data from other cities.

Elon really got this right from the beginning, but Waymo's aggressive PR and marketing have pitted public opinion against Tesla, as is very clearly evident even in these HN comments.
