Surely the easiest way to "charge per mile" isn't actually to charge against the car, but an extra charge on the cost of fuel? This would, obviously, require a different solution for electric cars, but for ICE cars, the more miles you do or the less efficient your car is, then the more you pay.
Surely that is the easiest way to do this.
Add 10p per litre. For a car doing 10k per year
For a car doing 40 mpg = £114
For a car doing 30 mpg = £151
For a car doing 20 mpg = £227
If they need more or less taxes, then adjust this charge. But that seems like the overall easiest way to do this surely?
Otherwise, as mentioned, going off the odometer could be easily altered. Maybe the solution is to scan the cars ECU every year, as I believe the true mileage is logged there. But then it'll just be a matter of time before that is hacked too. ICE cars I suppose you just keep a system similar to current VED rules I guess. You don't want to bump the price of all electricity, and it might be more difficult to distinguish between electricity to heat the house or cook the food, and that used to drive around in.
