You're right; certain hybrids, like the Prius, have proven their reliability over the years, especially in taxi fleets. However, it's worth noting that BEVs inherently have fewer moving parts, which can mean less potential for mechanical failure eventually.

Regarding FSD, I would not say that they are falling behind. It's an entirely different approach to the problem. If you compare Waymo rebo taxis and how the latest beta from tesla is performing, it looks like tesla is doing better.
