The British Deparment of Transport has come up with a new way to tax its citizens. To combat congestion, the Department of Transport secretary Alistair Darling is looking for a politically neutral deal to bring in laws that enable a satellite based road charging system. UK citizens would be charged between 2p and £1.30 (between 3 cents and $2.35+ USD) a mile for each road trip, depending on what road they use and the time of day. Such a system may not be in place for another 5-15 years, and probably not universal in the UK until 10-15. Luckily, public support would have to exist for such a system to be installed. It is an ambitious plan, and we wonder whether public support would exist for such an intrusive tracking system, let alone the chances for widely variable mileage rates.
