- This removes wasted police time chasing drivers of untaxed, uninsured vehicles.
- Removes administration overheads for the vehicle duty system, as the petrol price is already controlled by government. No complex rules about emission based tax levels.
- Incidents involving currently uninsured drivers would be much simpler to deal with (since they would have cover for third parties by default).
- Reduces wasted court time recovering costs from uninsured drives and dealing with compensation proceedings for the victims of incidents.
Remove separate road duty and provide 3rd party only insurance paid as part of the duty on petrol prices. This would involve a raise in the price of petrol, but is the ultimate pay as you drive charging mechanism without having any heavy process/technology involved. The more you drive, the more you pay, the more inefficient your vehicle the more you pay.
This removes all un taxed and un insured vehicles from the road.
Clearly most drivers would still buy insurance to provide comprehensive cover of vehicles.
