Future of what? Reliable mass public transport is the best option for a sustainable future. We don't need car centric suburbia but with heavier and more expensive cars.
Even if the US and other car-centric countries started a serious effort on that today, it would take decades. During which people continue to use gasoline cars, and emitting more CO2 we will need to undo in the future. Electric cars make sense right now regardless of your perspective on trains (I like trains, and dislike cars, and I am sympathetic)
I absolutely am on board with the idea... but reliable mass public transport requires an entire country of cities to be redesigned (this is in a country that struggles to get zoning laws changed to move from single to multi-family housing in many places), we'll have self-driving cars first.
Hell, I think we'd get flying cars first. It's nearly impossible to touch anything that requires modifying suburbs or their streets, politically.
We already have car centric suburbia and its going to take decades to change that. We might as well switch to electric cars which are quieter and produce less air pollution rather than wait for thousands of homes to be rebuilt.
except that mass public transportation is never going to happen on the needed scale in the US; electric cars is the next best thing and much preferable to the current status quo
you don't even need to agree on 'never' as 'not in the next 25 years' and 'never' both look the same for the timeframe we have to decarbonize personal transportation.
whether we have a world of 3 billion cars (doubling) or a world of 750 million cars (halving) in 2050, they all need to be electric.
