Firstly, thanks to everyone who's contributed so far I appreciate it. I would say there seems to be some mistaken assumptions and no questions.
Piece of mind doesn't translate to me as screaming match. I just used my words but It is natural to be upset when challenged. I didn't raise my voice he did. I said within earshot not the whole bus.
If you think it relates, I suffer from an invisible degenerative disease.
Stare at them and mumbling is not my preferred means of conversation but my illness presents sometimes that this is the only way I can communicate.
Thanks for asking the question. I was a passenger in a motorway accident where while the driver was performing an overtaking manouver was looking over thier shoulder and rear ended the car in front who suddenly broke. Isn't your primary responsibility to make sure the road in front of you is clear? (The direction in which the vehicle is travelling. When reversing is it not more efficient to look over your shoulder than using your mirrors.
I agree with the unpopular comment made by https://lemm.ee/u/SwearingRobin (Sorry, don't know how to properly link the comment)
I appreciate different situations require different behaviour but if you cannot maintain the 3 second rule so should your driving style be adapted?
