Pretty funny idea to fuck people's holidays for not having their tax/MOT etc up to date.
Less funny to also fuck all the people caught up in the traffic jam who are also going to miss their flights.
I feel like trying to catch people like this is a pretty inefficient way of doing it. Given that I can check my MOT and Tax status online, there should be a bulk way of doing this - and then joining that to the DVLA to get registered addresses of owners.
Appreciate you wouldn't catch unregistered cars this way, but you'd get the bulk of them surely.
