In most US states, auto registration and auto titles are two separate things, which means our automated traffic camera systems can mail the tickets to the people who are probably actually driving the car. But I guess it's easy for a country like Britain to lay that kind of burden on auto manufacturers when they don't have any of them anymore.

And besides, as other commenters pointed out, even if things get lost in the mail or the government otherwise drops the ball, they'll still consider that your fault.
