The well known view, still stands: scrap the VED, add duty to the fuel so it is relative to how much driving you do
I have supported that view for many years, especially when driving company cars many hundreds of miles a week, or over 100k miles in a year.
However, in 2017 we must review that opinion, as with a growing number of electric / hybrid cars on the road, the opportunities for the government of the day to generate tax via a usage petrol/diesel charge is naturally going to decline. For the next five years perhaps tax paid on fuel instead of VED is still a valid cause, but after that I don't think so. Over the next five years the answer is to implement road charging via ANPR systems, or by other means. Toll booths are so out of date, so electronic systems will be required, but with some form of security to avoid criminals using your number plate, cloned, such as a "fingerprint" / chip built into the genuine plate.
