You do realise the DVLA also clamp the vehicles of uninsured drivers, yeh... or would you rather they were out and about?
VOSA also clamp cars that have no MoT or are otherwise unsound. You want that crap on the roads too?
You do realise VOSA don't prosecute those drivers. Do you still want those drivers getting away with this. I've never heard of VOSA stopping an uninsured driver..
Also, you do know VOSA don't make any distinction between a roadworthy and non road worthy car or do anything about it?
