I’d be more enthusiastic about electric vehicles powered by fuel cells.
Can’t see hydrogen being much use as it’s not very energy dense and is a bugger to handle and transport, but ethanol would be ideal. And sure, you’ve got carbon in there so it’s going to emit CO2, but so long as that’s sourced renewably it doesn’t matter… the exhaust is clean, no nasty particulates or nitrogen oxides and you can refuel as fast as you do now.
