So don't use them. They're not mandatory and the open road remains yours for the taking, aside from motorways. But just as not all people are track runners, not all people are ex-bike-couriers, and it would be nice if they could ride a bike in something other than abject terror. Also, I actually don't favour a total ban for the most part, just pricing in the externalities. Which would make petrol and diesel powered cars astonishingly expensive. Removing a liter's worth of CO2 from the air would have to be priced in to the cost of a liter of fuel. Paying for your dead neighbour's funeral would need to be covered too (though insurance is meant to cover this, drivers who kill people walking or cycling are rarely found at fault, because it's legal to kill people with your car if they're in the street). Meanwhile, you'd still let the odd hot rod or classic car enthusiast have a project car to wrench on during the weekends, and honestly, I think that's great. They're a key part of our cultural history and great fun. But right now we still pay for all of those things! We just make _everyone else_ pay for them, which is very unfair. My taxes pay for the street where people drive too quickly to stop before killing my child if she slips from the pavement, and where they emit pollution that has rendered her less intelligent than she might be otherwise, though it's impossible to say by how much. I don't even own a car. So that seems unjust.
