Combustion-powered vehicles are something of an exception, because only a small fraction of their pollution is associated with their creation. Buying a new car every few years probably isn't optimal, but operating an ICE vehicle for decades probably isn't optimal either.

In Brazil, cars run on ethanol. Emissions associated with combustion of the fuel are zero. It's not the ICE bit that's a problem, it's the fossil fuel part.
