You're greatly overestimating the difficulty of migration of diesel to petrol. Also you say to "give it time". Why, that's 30 people a day, a Grenfell disaster every 3 days. Will you personally apologise to the families of the 30 people every day that are dying from complications related to diesel exhaust, and that giving it time while their loved ones die is the best solution? I'm assuming you either drive a diesel vehicle and are against financial burden to yourself, or you love away from an urban centre where you are happily naive to the actual impact diesel exhaust causes to yourself. (or maybe you're lucky that diesel fumes don't affect your lungs and heart the way they do many others like myself). A £500 pound annual fee for all diesel vehicles, to be upped to £1000 after one year, will go far to motivate diesel owners to consider other options and make "the right choice" on next vehicle and fleet. This could also go straight towards the NHS to offset treatment for air pollution health issues. Did you see what I wrote about CarGiant? Diesel cars are easier and cheaper to buy right now. You have to go out of your way to get petrol instead of diesel. This law is basically putting the status quo on hold for a decade or more, because no politician wants to be the one putting his or her name on a bill to cause financial burdens on diesel owners. Yet they have no problem continuing to poison the rest of us.
