not a tank
um look at that thing above
it is street legal
it's not too wide, it has all the mandatory signal lights and headlamps, and has rubberized tracks, as well as periscopes to look out of, and only weighs 6.3~ tons without being fully loaded (your average semi-truck is 9 with a trailer). with some modern engine replacements it'll also easily make 100 km/h
at least in Canada, it can be and probably is legal.
