I agree. They won't become the norm, but lets say for the sake of arguement they did, the government could tax you UK inhabbitants for the disposal of the batteries. Apparently there is no environmentally friendly way to get rid of them. i think hydrogen is the way to go. Or what about NOS? Isn't that nitrious oxide? If that can make cars go faster, than just make them run off it maybe?
N2O is an oxidising chemical. It is not a fuel. What a lot of people don't realise is when you have a nitrous kit, it also injects more fuel (diesels are a little different but they still need something to combust with the nitrous). Without the extra fuel then the nitrous doesn't do a lot.
This means that you will never be able to run a car on nitrous alone.
Ah ok
