This doesn't follow.
If you were truly ecologically minded, you'd cheer on all the automakers in their move to EVs, not one in specific with a microscopic market share. BMW has more potential to shift the landscape than Tesla.
I highly doubt the EV efforts would be nearly as far along as they are without Tesla, and the danger that the catch-up activity by other players dies down again if Tesla goes under is very real. (until the Chinese manufacturers start tackling the European market, that is)
There is nothing better to put pressure on other manufacturers than a successful EV vendor.
Also, Tesla's market share is no longer microscopic and the likelihood is its going to continue to grow. Thats the whole point of the market valuation that this conversation we're having is about.
Comparing the indicative with the indicative mood isn't fair. Vapourware always/never beats what's shipping.
When another automaker starts selling an all-electric lineup, I'll cheer for them as much as for Tesla.
By "right now" you mean for a single historical quarter, in one specific, shrinking auto segment (sedans), in one global market right (USA), correct?
Because, again, BMW sells 250k vehicles globally, per month. Torture the data enough and anyone can be a leader.
