The immediate impounding of an apparently uninsured vehicle replaces the former method of dealing with insurance spot-checks where drivers were issued with an HORT/1 (so-called because the order was form number 1 issued by the Home Office Road Traffic dept). This 'ticket' was an order requiring that within seven days, from midnight of the date of issue, the driver concerned was to take a valid insurance certificate (and usually other driving documents as well) to a police station of the driver's choice. Failure to produce an insurance certificate was, and still is, an offence. The HORT/1 was commonly known – even by the issuing authorities when dealing with the public – as a "Producer". As these are seldom issued now and the MID relied upon to indicate the presence of insurance or not, it is incumbent upon the insurance industry to accurately and swiftly update the MID with current policy details and insurers that fail to do so can be penalised by their regulating body.
If the younger driver is covering his own costs, it might be cheaper for him to take out his own policy but include one of the older, lower risk drivers from the household as a named driver (as long as the older drive will use the car). However, if the older driver is footing the bill for both policies, multi-car insurance may still work out cheaper.
Several jurisdictions have experimented with a "pay-as-you-drive" insurance plan which utilizes either a tracking device in the vehicle or vehicle diagnostics. This would address issues of uninsured motorists by providing additional options and also charge based on the miles (kilometers) driven, which could theoretically increase the efficiency of the insurance, through streamlined collection.
