I think it’s definitely dangerous to use your vehicle to make a point.
It can be very dangerous. I remember when I was about 13-14 my dad was driving us through France. Ahead at the side of the road he saw a drunk woman. There wasn’t a path as it was a very rural location but she was well over to the side but was wobbling a bit. My dad seemed to take offence to this and decided to pass her as close as he could to shake her up. I remember distinctly being really scared as he didn’t seem to be giving her much room at all.
He passed her so closely that the wing mirror hit her arm and broke it while sending her spinning. The Police were involved and my dad claimed she fell into the road as he passed. I knew that was crap, as did my brother, my dads new partner and her daughter but no one dared call him on it.
We haven’t spoken in years, but you get a nasty person who uses their car to make a point and people can really get hurt.
Edit…I also remember the conversation we had in the car as he approached…we were pleading with him not to pass too close to her. What a massive dick.
