Waymo has proven driverless operations in Chandler, then Downtown Phoenix, then San Francisco. Truly driverless, no people in car. They’ve demonstrated driverless capability and the ability to expand to new regions, even if it means taking HD maps.
Tesla has not proven any reliable driverless operation, anywhere. They have removed hardware from their cars (radar, uss) and have not shown any meaningful progress in the past ~5 years nor any willingness to change from their “vision only, big data” strategy.
If things continue on the current trajectory Waymo will likely be operating in all major US cities and metros in a few years while Tesla’s self driving offering will probably be forcibly renamed by regulation and end in a class action lawsuit.
Basically, Waymo has proven N and N+1 capability, meanwhile Tesla has yet to prove N, and has lied to consumers and actually reduced their chances at achieving N due to cost cutting measures.
