Your last statement meaning about companies that went belly up? If that's what you're asking for an explanation of my take is this: New technologies, when they're especially new and especially unproven, have lots of failures - because they're new and unproven and not well understood. I'm not going to try and justify any sort of bad government programs that didn't produce results - because they're not justifiable.
You stated there are studies that show total lifecycle ramifications of gas cars is lower than with electric vehicles. I've found the opposite. Below is a link to one. My understanding is the production of the EV is harder on the environment than a gas car, but factoring in differences in operation (including extracting oil, refining and transport of the gasoline) swings the advantage balance to the EV side.
Progress is being made on numerous fronts to improve the EV ecosystem: New chemicals are looking positive to base batteries on. Coal (which only accounts for 20% of US electricity production) is being reduced. The lifespan of the batteries, I believe, will be longer than what many think. People will often point to an 8 year battery life. That's how long the warranty is - not the lifespan. I've heard anecdotal stories of Teslas with hundreds of thousands of miles on them. Lastly, with home solar systems becoming much more prominent, those systems can be (and in my case is) the basis for charging the car. We cover approximately 80-90% of our daily driving needs without pulling any electrons from the grid.
The bottom line for me is this: I've seen a lot of technological advances in my life (as have we all) and I believe EVs are in a state today where, while clearly not perfect, are on the path for massive advances. I think there's sufficient interest and demand from the market where car companies and the market will keep improving on them...in all areas.
