1) New models will obviously have more range than ones 4 years ago... My point was the Tesla Semi should be treated as incremental rather than revolutionary, just like releasing a new smartphone model with more RAM than one 4 years ago. Also the Tesla Semi hasn't even launched yet so they can easily overpromise making comparisons with any existing offerings difficult.

2) As with Ford for ICE vehicles, affordable EVs selling higher volumes are much more important to than the premium EVs offered by Tesla in terms bringing the tech mainstream. In this way, BYD and Nissan should be credited much more than Tesla. In terms of contribution, I would put BYD much higher than Tesla: BYD manufacturers their own batteries, sell more vehicles, drive industry competition in the much more relevant CN market, and their success influnced the Chinese government to phase out ICE cars.

3) My post was specifically replying the the person above who was worshipping Musk on a pedestal and giving all the credit to Tesla.
