I hate this. Just driving along a dual carriageway and stopped at the lights before turning left. Lane to the right of me had an oldish woman and a 40 something man behind in a BMW. Because she didn't fly off like Max Verstappen he sounded his horn for a long time. She wasn't even slow.
I thought this was against the Highway Code and should be sounded as a warning only not a rebuke? It made me think someone was in danger of hitting a child or something.
