Please don’t drive up behind people and bib your horn if you are driving silent car Number one they may be deaf and as a motability driver should be aware that not all disabilities are visible it could give someone quite a shock.
With the woman in the supermarket car park, she heard the blip of the horn, moved out of the middle of the access roadway & I thanked her verbally, everything was fine, but I get your point.
As for frightening the parking attendant, well that’s fun, and as he was a man it’s an added bonus, he got a smile at least. I admit to being a bad bad woman, but I left all these people with a smile on their faces.
