I wouldn't have such a problem if they applied it just to new cars or even existing cars when they next change hands (although it would hit resale values), but to apply it retrospectively to the car in your driveway is plain dishonest.
Agreed. Especially when previous changes to the banding were NOT applied retrospectively. If their motivation is the environment, they should be looking to discourage the purchase of new cars with high CO2, and the use of cars in general. (and a 1K first year road tax is not going to do that. It will probably be swallowed by the dealer as a sweetener.)
Once the car is on the road, milking it for more road tax is just taxation and can't be dressed up as concern for the environment, etc.
It's a shame the media whipped up such opposition to the rise in fuel duty, tbh, because that seems the obvious answer. Having said that, more taxation is not what this country needs. A clear indicator and some commitment as to what long term plans the government has for transport would be good, and would promote investment in the right areas. Sadly, I suspect this shower has no long term plans, other than to continue to use the motorist as their Cash Cow.
