What alternative do you propose? Fossil fuels are out because of climate change. Hydrogen is out because of terrible energy efficiency. Synthetic fuels have even worse efficiency. A massive reduction in car ownership probably won't happen in the next twenty years either.

Cities should be built for people, not cars. If people lived in cities that are as dense as pre-automobile cities were, most people could get by without their own personal automobile. Trains are relatively efficient and clean. I think of asphalt as a waste product of petroleum refining. What are roads supposed to be paved with, when there is not any asphalt to cover them?

  That is of course a good idea that I fully support, but remodeling cities will take way too long to meet climate targets. Also, a rather large fraction of the kilometers driven don't happen in cities. Public transportation in rural areas is quite difficult to set up because of the low density.

@adrianN cheap, efficient vehicles with far less electronics, think VW Beetle, very basic, frugal and easy to maintain. ICE engines have never been more efficient, while EVs are at a very early stage of mass viability. I also feel connected cars should be optional, we are staring into a near future where all travel will be pre permission based and controlled via this apparatus which also tracks your every move regardless of power plant. The most urgent elements of EVs that need to be looked into are fire risk and control of wrecked vehicles, toxic battery element mining, processing and disposal and cost as previously mentioned. The sheer weight of EVs make tire pollution (a massive problem in urban areas from all vehicles) a big concern. All cars should revert back to a far more recyclable manufacturing state: the alloys and plastics modern vehicles are made from are not

  Sure, smaller, simpler, more recyclable cars are good. But ICEs are a no-go for climate change reasons. It doesn't matter if they're more efficient than ever, there is no viable path to get them carbon neutral.
