There are a lot of reasons for banning this beast and frankly some of the lessons are rather old.

For example, in the '80s the UK military stopped using military number plates on "family" vehicles outside the UK. Yes, we used to rock around in Germany in a family car with UK military plates - that's pretty daft. We switched to UK standard plates. So you had left hand drive cars with UK plates. lol

Anyway, its now modern times and we now have cars that would challenge a 432 for mass.

A Cybertruck is sharp edged, cruel and hard and will kill whatever it hits - "It will cut". That is not welcome outside the US. If you want to drive an armoured car then buy a proper one. I suggest something like a Saracen - https://en.wikipedia.org/wiki/Alvis_Saracen or "Warthog".
