It’s not breaking the law to make gestures and wave your arms at a deliveroo bike or skooter whizzing by you,if they fall off killing themselves you can’t be held responsible,we all would be in court.
I'll take your post as being tongue in cheek but I believe the law changed not so long ago and it's now an offense which may even cross over into being classed as road rage -
Being abusive or making rude hand gestures to a fellow road user or pedestrian can be
considered inconsiderate, careless or dangerous driving.
I knew someone about 15 years ago whose wife was verbally abused by another driver, it was actually a bus driver who did the same trip every day (think he may have actually been the school bus driver)
This lad decided to go down the next day and have a word with him and they got into an argument about the bus driver making personal insults to his wife
Anyway the whole incident somehow got reported to the police and this lad was questioned about it, the copper then asked him how he had gone from his house down to the bus stop to confront the bus driver and he replied "I walked, why
", the copper then said that if he'd driven down it could have been classed as road rage even if he'd parked up and got out to speak to the other driver.
How true that actually is I can't be 100% as the copper may have just been trying to shit him up a bit but people need to start realising that what they think may be a fairly tame 2 finger salute could actually have more serious consequences
