Would you apply the same same restriction to anyone with a gun in their possession troll?

I rather assume you do. But restrictions on gun-users seem to be seen somehow seen as less acceptable than restrictiions on car-users by some people.

And I take it the same rules would apply to alocohol abusers? After all the evidence about adverse efects on driving is a lot stronger there. If it hasd been in force back then of course it'd mean Baby Bush would have lost his licence to drive for life of course. I think most people could live with that consequence anyway. (And unless I'm very mistaken he was pulled in in two occasions, so that would have been five years in jail...Better still.)

And I think that any-type-of vehicle-in-any-circumstances would be a bit harsh. Presumably it'd apply to people riding push-bikes or roller-skates or skateboards in parks, or with a sit-down lawn-mower in their garden. Push-chairs could be a problem too. Would riding a horse count as a vehicle?
