Because Tesla investors need to be lied to that they have a unique edge over the incumbent manufacturers.

For incumbent manufacturers it is an all or nothing proposition. They have to abandon their ICE lineup. It looks like they are standing still because of that but the rate of change can actually be much faster than at Tesla because once they abandon their ICE lineups there is nothing but EVs left to manufacture and they will manufacture them at exactly the same rate they manufactured ICE vehicles.

Those cars will actually be carbon free in Europe in the following countries: France, Sweden, Finland and Island. For most of the others it's actually a lie.

Your car is "carbon free" if the electricity you put in is carbon, or close to carbon free. That's it.

38% of Europe's electricity was generated by renewables in 2020 - not including nuclear. This proportion is growing rapidly. It's a win already particularly given the relatively poor efficiency of internal combustion engines.

And it will only get better as a virtuous cycle between the growth of renewables in generation and the growth of BEV ownership. Off-peak EV charging provides a valuable sink for cheap off-peak renewably generated electricity.
