You're telling people not to listen to Ford PR, and instead pointing them to a podcast by a higher-up at Tesla with a very clear bias and incentive to talk shit about competitors? Dude...

Waymo can scale as fast as they want to via partnerships like the one they have with Chrysler already. Other companies will build the vehicles and add the hardware, Waymo will handle the software. Not everyone has to do everything in-house like Tesla does.
