any U.K. resident driving a U.K. registered vehicle on the continent twice in a year, more than six months apart, could have their vehicle impounded abroad

Based on an E.U. Directive and therefore will also apply on the continent. Therefore any U.K. resident driving a U.K. registered vehicle on the continent twice in a year, more than six months apart, could have their vehicle impounded abroad - indeed, possibly, in several countries, if they drive through several.

The implications are horrendous. It is going to criminalise thousands of decent people.
