We really, really have to stop blaming everything on covid. I've heard it all now blaming bad driving on covid. There was endemic bad driving long before covid! Driving standards have been falling for years, probably decades.
The only link with covid is that the incidence of bad driving is exponential (like covid spread was). That's because the more people observe bad driving, arrogance, beeping, going through red lights, speeding, etc., and see for themselves that there's ZERO enforcement, the more they do the same themselves!
Add into that, piss poor road design, poor traffic light sequencing, unnecessarily low speed limits, barely visible road markings and signage, and you've the perfect storm for an epidemic of bad driving.
Oh, and add in loads of incompetent drivers (the kind who stop at roundabouts BEFORE thinking/looking whether it's safe to proceed), elderly drivers who shouldn't be on the roads, people on their phones whilst driving, people driving at 25 in 40/50 mph zones, those that carry on driving at 30 completely unaware the speed limits changes between 20,30 and 40 along that road, etc. It's amazing that driving behaviour isn't a lot worse than it is really when there are so many numpties on the road who are oblivious to other traffic, signage, conditions, driving rules, etc.
If you think driving is bad in the UK, you should try driving in some other countries!
Back to the OP, if you've been beeped 3 times in one day, sorry, but you're the problem. I can't remember the last time I was beeped at all - must be a few years. I do remember being beeped about 5 years ago when I wasn't concentrating and found myself in the wrong lane, and didn't check properly before starting to pull into the other lane, where there was already a car alongside me - he quite rightly beeped at me, and I fully deserved it!
I'm all for compulsory re-testing every 10 years or so along with getting the police to start policing the roads again. Policing used to be done by "normal" police, but now they ignore driving offences and it seems only the dedicated "traffic" police will deal with offences usually during "campaigns" against specific things, you have to be doing something really, really, bad to get a routine patrol to stop you these days. A couple of decades ago, you;d get stopped for a light out, or going through a red traffic light, or just if you were driving badly to be given "words of advice" - that doesn't happen anymore.
