I dont understand how you can agree that this is a good idea, it is another measure to increase surveilance on our supposed "free" lives.
We are already victims of the "big-brother" syndrome, with the CCTV systems JPreston mentioned, and the use of mobile phone trackin, albeit with an appropriate court order.
If this planned action gets the green light it will be a farse, we already pay road tax, doesnt a part of road tax pay for road maintenance, we also pay council tax, which again a percentage is used to maintain highways, roadways and public footpaths.
This would be another payment each month that accumulates towards the growing cost of owning a car, including car insurance, services and reqular maintenance.
Again if this goes ahead, they will only taxate this scheme with green awarness in mind.
I have no problem with paying to do something i enjoy, which is driving, and im not anti-green either, i recycle practically everything in my household. But i will not agree to another cost to an already highly expensive means of transport.
