They partially solve the fuel and the bad air problems. In exchange they damage roads way more (I recall reading that the damage is proportional to the vehicle weight to the fourth power, probably with some more nuance) and that also creates substantially more rubber micro particle pollution. They also happen to be more dangerous in the event of a crash. Plus the additional challenges with grid load, which some people dismiss with silly ideas like having said cars act like load balancers (that would be a mess to scale).
In most cases, EVs are not a solution to mobility, they are a solution to save the car industry from real solutions to climate change, namely spamming trams, trains and buses (in sparse locations) all over the place.
However, EVs only change one aspect of cars: How they go vroom vroom.
They are still heavy metal boxes operated by random people. Most drivers suck (myself included probably), they are lazy and don't follow the local law on driving.
They are absurdly dangerous, for people inside other cars, themselves, and pedestrian. Anytime someone goes too early with their car it's potentially an accident with death causes. Same if they spin their funny wheel a little too much.
Imagine yourself overtaking a car on the highway. Now let's say the driver slips by accident, wheel stairs to your sidey giant death machine crashes yours from the side, and its a horrible accident.
Besides that, car infrastructure is absurdly expensive, and becomes even more expensive Everytime it needs to be renewed. The city I was at school at is literally one of the poorest in my country after having endless money in the 70s, because they built too many roads. They built some roads not on the ground but in large pillars, and it's literally falling apart.
Lastly, cars take up tons of public space. Cities designed (or rather bulldozed for) cars sprawl, need huge parking lots, huge streets, produce noise pollution, regular pollution.
There is much more but that should suffice for now.
That being said, I doubt we can ever go truly car free. Remote regions do not have enough people for good public transit to be maintainable, and the distances are often too long for walking or biking. Deliveries need some kind of individual vehicle. Some of that can be addressed with EVs and car sharing.
Sadly, EVs are being presented as the all around solution.
Ironically, cars are stopping me. Roads used to be for walking, and now they’re for cars. They gave us sidewalks and now some places don’t have them, and are unwalkable. The bike lanes either don’t exist or are too dangerous to use. It’s all roads and stroads now, with speed limits dangerous to pedestrians, and large SUVs meaning that car crashes with a pedestrian are more likely to end in death.
The amount of people in cars has also crippled public transportation. Buses aren’t quick, and there are so few of them in general. Not to mention the lack of high speed trains, and the inefficiency of our subways.
Giant parking lots with no cars took our parks. Took our public spaces. Took our nature. And they’re everywhere. Everywhere I look is dull, grey asphalt.
It’s depressing to be outside. And where would I walk to? Everything is too far away to walk to. It used to be a 5-15 minute walk away. Now it’s more like 40 minutes to hours...
I’m tired of human interests and public transportation being overlooked so that people can drive a couple minutes faster to their destination. When people in Europe, Japan, and China can just… get on a train.
I literally do that to go to work and university. I walk to my local train station 20 minutes and it's amazing that I can. It makes me wake up, even as someone who hates to get up early and gives me time to listen to music, podcasts or think about personal stuff.
That being said, it's not true that no one is stopping me. All those idiots that park in the sidewalk are stopping me. All those idiots that endanger me with their crappy super heavy metal boxes are stopping me. I literally have to stop when I want to cross the road.
And besides that, walking is only possible if you don't live in a car infested hellscape (luckily I do for the most part). Otherwise, the next destination is hours away by walking, rendering it pointless, and walking becomes very dangerous.
