Bankrupt doesn’t mean the company goes away. Most if not all existing car manufacturers have gone bankrupt at some point or the other.

That said, of course this does not resonate well with the costumers, but where is the competition anyway? Still 2-5 years behind... Plus the EV space should grow, right now it is only 2% of the market, that leaves a lot of room for all the brands to flourish. Just look at first hand experiences here, once you have tasted EV and if it fits in your transportation needs, there is no going back.
