Increase in fuel tax as such fails to take account of WHEN one is driving or WHERE one is driving. My proposal with partially deductible fuel tax (which some seem not to have read with sufficient attention) cannot deal with these variables, but is otherwise appropriately progressive and hugely less invasive.

If my mmory serves me the data protection moguls have queried government collecting all that data too..., but politically "the right to speed" does not go over well!

Of course, if speed limits were sensible, eg 90 on motorways and not less than 50 on rural B roads (I live near an A road with no villages on it where the speed limit is 40(!) which is why everyone breaks it. If it was 50 a few might observe it) I might even approve of average speed cameras.

How about a black market in duplicate bugs you can leave at home while you go out with the spy in your car turned off??
