I’d never pull over for ‘some guy’ who gets angry with me, until I hit the boundary of my own property.
On the other hand, if he’s angry for some reason and I get stuck in traffic with him behind me and he gets out and comes toward me with a tire iron - all bets are off.
Right! Of course it's best to avoid the situation in the first place.
I was setting up a situation in which brandishing might be the best choice, just to ask the question.
