Elon never cared a bit about environment and shit, that’s why he wants to land on some other inhabitable planet.
It just happened that there was a void in the market and Tesla was at the right time, introducing expensive luxury ev with long range when the only other options were expensive shitboxes with limited range. Suddenly there was an option to get something that would be worth owning at that price range.
If he really cared the environment he would push for a small and light city vehicle instead of a huge heavy truck with a giant battery that can’t be used for actual work
