My normal reaction these days to someone who does something annoying whilst I'm on the bike is a sad shake of the head, which in my mind conveys utter disappointment at the actions of the individual. They probably don't notice but it makes me feel better than shouting or arm waving.
The few that do notice sometimes apologise with a shrug or a wave of acknowledgement. The others don't give a toss.
A long time ago I was forced into a kerb by a bloke in a luxury SUV while he was on the phone. Once he'd stopped after noticing my frantic bashing at his passenger door I asked him if his Bluetooth was faulty. He had a meltdown, a big sweary meltdown. I'm not a big bloke or intimidating but tellingly he didn't get out of the vehicle to confront me while I smirked at my excellent quip. <insert raised Roger Moore eyebrow>
His utter rage at my smart-arse remark was a sight to behold, especially as he'd almost crushed my bike.
My partner (who's a psychologist) reckoned his rage was probably at himself and his own failings more than anything else, Oh and he was probably a tiny-dicked-virgin.
