Public policies

In many jurisdictions it is compulsory to have vehicle insurance before using or keeping a motor vehicle on public roads. Most jurisdictions relate insurance to both the car and the driver, however the degree of each varies greatly.
Several jurisdictions have experimented with a "pay-as-you-drive" insurance plan which is paid through a gasoline tax (petrol tax). This would address issues of uninsured motorists and also charge based on the miles (kilometres) driven, which could theoretically increase the efficiency of the insurance, through streamlined collection.
