> If you compare a Tesla with a BMW, the Tesla already might be cheaper, it certainly is if you consider the TCO

Having owned a few BMW's I do not doubt that assertion at all.

Hydrogen has a storage problem. As in the stuff is wickedly hard to keep from 'evaporating'. Electric has a charge time/range problem. I can fill an ICE car in 10 mins and drive 400 miles. The same thing with electric takes an hour. For 'day to day' use electric is like almost there (up front cost being one of the bigger issues). For long range drivers, not yet.

Plus a semi can haul like 5tons more instead of dead weight. I can see batteries working for regular cars but for trucks no.

The weight difference for an electric Semi is rather 2t or less. Also, slightly larger total weights could be allowed for electric Semis.
