I don't trust these estimates. By 2050 there's no way regular ICE cars will be common. Once any given region goes past about 33% electric vehicles gas stations won't be profitable anymore and will shutter forever. When that happens it'll be like falling dominos as gas prices go up and more people will purchase electric vehicles out of necessity as ICE vehicles will become unaffordable.
I also seriously doubt these estimates are taking into account the fact that battery technology and the rate of battery manufacturing is improving at an exponential rate. Yes, the curve is shooting up that fast!
Also, this title is missing a big problem that all vehicles have: The tires are one of their biggest sources of pollution.
