I find if someone has made a mistake (usually one that anyone could make/ has made) honking is probably not going to help them at all - it will just stress them out more. That comic is exactly right - we can rage about others all we want, but what's the point? We all make mistakes. If someone cuts me up it's usually because it's REALLY hard to get out of that junction/roundabout any other way. If no harm is done, I'm not gonna get mad about it.
But 3 things of note:
1. I work in Roundabout central - Milton Keynes has to be the easiest city in the UK to drive around. Grids and roundabouts, dual carriageways and plenty of room. I'm sure Huddersfield can't be that bad - I saw plenty of considerate drivers around Sheffield.
2. My route to and from work involves a LOT of situations where people are parked on the road so only a single lane of traffic can get by - people have to wait, so giving a polite "thanks" or "You're welcome" is a daily occurrence
3. I get road rage approximately once a year, in exceptional circumstances only.
Only if someone is a MAJOR douche will I get ticked off about it. On the whole I just don't get the deal with road rage. If you really pay attention to the considerate things other drivers do, I assure you it's a lot more rewarding.
Like 99% of Brits I only use my horn in those extremely rare occasions where someone has done something illegal and/or genuinely dangerous.
So anyway - this is a thread about reverse-road-rage - to celebrate the thoughtfulness of other drivers.
