Electric cars just replace a car with another car. I’m not even convinced we need lots more public transport, at least not long-range public transport.
This is the same argument that results in the majority of software created being slow stupid trash. “We don’t have time to fix those major architectural problems that are going to grind improvement to a halt later, we need to release this new stupid feature yesterday because line must go up.”
That statement is just straight out false. Yes electric cars still represent a huge deal of energy needs for producing, but they are much, much more efficient at using energy than ICE cars. If I remember correctly it was something like 40% vs 90% energy efficiency? That’s why if you put several electric cars connected in a row, place them on tracks, externalize the power source, and you get the most efficient way of travelling - trains.
The (urban) issue is the space they require when not in use. Public transport and cycling require a lot less parking space. Shared (quick easy short term rental) electric vehicles are quite a good thing too.

Sounds right when said like that, but I think very important factors are missing in that comparison. Maily: energy used per person & space used per person.
Most cars on the road are only transporting one person (the driver), which leaves a lot of wasted space. Trains on the other hand can carry way more people than cars can when using the space amount of space.
I don’t know energy used per passenger but it’s certainly less for train vs car (when both running on renewable energy).
Apparently (I think C02 emissions should give us the same idea if we assume both use clean energy):
Eurostar: 6g CO2e per passenger km
Electric Car: 53g (one passenger) CO2e per passenger km (or 13g with 4 passengers)
Don’t think a lot of trains are as clean as the eurostar worldwide but it’s possible to be that clean.
Theres many more benefits to trains too such as: You don’t have to drive (browse lemmy while travelling), cheaper, 20x safer, a good train system can save you time, less waste (when your car eventually is scrapped, I’m sure a lot if recycled, but must still be a lot of waste, including energy spent recycling). Probably a lot of other stuff too.
p.s. sorry if i am wrong about stuff im trying to be right ;()
Electric cars have very little upsides compared to gasoline cars. They’re basically made for the car industry. Not the consumer.
What we need is more cycling and public transportation.

Especially long range. International/Interstate high speed rail should be the norm.
We can replace a lot of existing cars in single digit years it will take decades to build out transit everywhere

You actually always have to take care of near and long term in any real world situation.

But that’s neither better nor worse than ICEs, not really the point we’re discussing
Exactly part of OP’s point?

Yes, electric cars are just like trains
ngl you had me in the first half
