Zulu,
Who died and made you nanny of the world????

There are lots of former military vehicles on the road and they do just fine thank you very much. Think old Jeeps. FYI ANY vehicle on the road is a danger to others on the road when mishandled. Just the simple fact of momentum and force makes that the case.
I suppose you want to ban the ownership of former military aircraft as well. After all no one NEEDS a P-51, F4U, FM2, F4F and so on. After all, airshow are just a waste of fuel aren't they.
Come to think of it no one NEEDS a vehicle larger than a volkswagen beetle (old style) so everyone should just get that and forget about freedom of choice of owning anything. Right?
