Elon Musk raised billions of dollars to research, develop the technology, build the infrastructure and manufacture electric vehicles. The man has well known and documented personal and business deficiencies. However the fact that doomed Tesla was that there simply is not a profitable market for electric vehicles in the United States. Most consumers want the reliability and convenience of the internal combustion engine. Unless coerced they tend to shun electric vehicles.
There is little doubt that Tesla will eventually go bankrupt. However the market forces that doomed Tesla are already hurting big auto manufacturers such as Ford, GM and VW. These companies like Tesla have made huge investments in EV research, technology, infrastructure and manufacture. They have had virtually no return on those huge investments. The money is dead and squandered. These companies are suffering as evidenced by the recent contractions at Ford. IMHO the auto industry made a very bad investment, are being dragged by debt and will be suffering mightily.
Not to mention the fact that the other car manufacturers are getting into the electric market and providing options that are much lower cost than Tesla. In particular, they are adapting existing body styles to electric and leaving out the self driving tech that drives the prices up. Also, since they are just getting into the gig, the rebates are available to prop them up.
The rebates exist for each manufacturer and phase out as that manufacturer sells a certain amount of vehicles.
Ford (and probably others...) has an interesting idea. They're going to market electric vehicles on the same platform as all the rest of their models. Where EVs have been a separate, niche market in the past, Ford is going to market "Electric" as just another powertrain option. For instance, you buy an Electric Explorer, instead of a V-6.
Sez me, that might work. People would switch at their leisure, instead of being pushed into adoption.
I'd certainly consider electric for some cases - for instance if I drove in the city 90% of the time, or just needed a simple grocery-getter, or as a second car. Heck, for years my grandfather had a Cadillac for a main car, but more often than not used his golf cart to get around in the retirement community where he lived. As did most of his neighbors.
