We've still got to contend with the horrible environmental effects of tire dust - EV or ICE.
And the urban sprawl from car dependancy, the salting of the roads, stormwater run off from roads, the wasted urban space that is massive surface parking lots, and noise pollution from the tires. EVs solve very few problems related to cars.
That's really the biggest issue that's unfortunately not at the forefront. Sure, EVs are much more energy efficient and therefore less polluting in the form of fossil fuel burn, but the way we travel is incredibly inefficient given the available technologies. Our country was literally built on the railroad, yet there is very little reasonable passenger rail alternatives in much of the country.
Isn't the lifetime difference something like 30% better than ICE? It's definitely better, but it isn't significantly better.
Turns out bringing 3000+ pounds of steel with you everywhere you go is ineffecient regardless how it is powered.
I've heard cars described as metal overcoats. People slap them on for the slightest reason.
I'll use my two, similar sized cars as an example (Subaru Outback and Hyundai Ioniq 5). Typical driving gets me around 8 L/100km in the Outback and 20 kWh/100km in the Ioniq. This NRCan site gives a conversion factor of 8.9 kWh/L of gasoline.
So, the Ioniq, at 20 kWh/100km is then about 72% more efficient than the Subaru at its equivalent 71.2 kWh/100km.
Even when considering lifetime emissions, EVs still have roughly 50% less emissions than ICE vehicles.
However, going back to my original point, person vehicles are still incredibly inefficient overall, given the potential alternatives.
Is there any notable development on that front?
Trains? Trains are great - and buses produce a lot less tire dust per passenger.
Building communities that are walkable? I mean, we could try that, but it wouldn't make rich people richer.
One crisis at a time PLEASE. Affordable EVs first, THEN flying cars.
Trains. Trains are the solution.
