Humans do a lot of dumb, irresponsible things on the road, but this is not one of them.
This cop[1] tells a lady not to stand between the vehicles because she will get killed if his patrol car gets hit, and seconds later it happens and he says "just like that".

Just like anything else, it may not be common (or it may be 'uncommon') but, to say that it never happens, is plainly, clearly and objectively false.
