I kind of wonder if it is that simple with regard toward driving others out of business too. It seems like most incumbents have already started to go electric so while they may be late in the game, it doesn't necessarily mean they get kicked out of it right?
Not necessarily. Given the long lead time to build automotive factories, battery factories, and mines, it's *very dangerous* to be too late in this transition. I think it's moving very fast. Some of the late movers will likely survive; most of them will not.
I've been gaming out the fleet transition. The first big point is the arrival of the Bolt and Model 3. After that, sales continue to be production limited. But the highest-margin top end cars are switching to electric so profits start to crater at the old line companies, giving them less and less money for investment.
The second big point is when electric cars essentially take over the top half of the new car market. A few years after that, I expect that the used electric cars will displace most of the bottom half of the *new* car market. (Thought experiment: at the same price, would you rather buy a nice 3-year-old used Model 3 or a new Toyota Corolla? Thought so....)
If you're a car maker and you haven't got good BEV or PHEV offerings by then, you're doomed.
The third big point is when the gas station closures accelerate and gas stations become hard to find. I think this happens in roughly the same time frame. At this point, even having PHEV offerings doesn't help you, you have to have good BEV offerings.
