OP – it doesn’t matter what we think or what you think – your wife thinks you’re being ‘angry man’ in public spaces.
If you continue to behave in the ways that make her think that she will continue to think that, however justified you believe you are in your behaviours.
You have a choice – behave differently and earn her approval or continue with the behaviour and accept her criticisms.
fwiw my pov: the first incident I’d have kept schtum or asked the station staff to intervene. The second was all a bit of willy waving on both sides but using the car as a weapon to try and move you put you on the moral high ground.
