I am a supporter of alternative fuels but currently there is no choice. It will take time to introduce choice. Electric sounds great but it is totally impractical for many people who need their car for work. Who wants to stop for 2 hours to recharge every 2 hours while on a 6 hour drive? Not everybody has a garage where they can charge their car, most people just park in the street. Petrol does have some advantages over diesel but diesel also has many advantages over petrol. Hydrogen etc. are far too new to talk about. I hope that we will continue to advance but often these moves are counter productive. Currently the best option for most people that actually do have a garage is a hybrid which still uses fuel. Diesel prolongs the life of the vehicle and is not a fire hazard which makes it a better option in a hybrid. The electric BMW i3 has a petrol generator to double the range, would that be banned? I think that these ideas are jumping the gun and we should all calm down and start taking baby steps toward a better future in order to avoid throwing the baby out with the bath water.
