Unsafe tailgater.
If I had to brake for some reason you would no longer have any 'no claims' bonus! Why follow so closely? You still had to stop at the lights up ahead.
Aggressively cut directly in front of a fully loaded 44-tonne articulated lorry from its nearside blindspot; just as it begins to move forward in traffic queuing at lights: and then go into road rage? You, "sir", are a hazard to yourself and all other road users!
Nice care but every time I see it the old white haired guy driving it appears drunk! Has zero regard for any other road users.
