Wether its a calm "what's this cabbage up to?" or vein busting anger outbursts at the wilful dangerous stupidity you just witnessed, what is it that people do when driving / sharing our roads that annoys you the most?
Hoons? Speeding? Driving too slow? Drivers on phones? Right lane hogs? Inattention? Failing to stop, give way, indicate? Cyclists?
Riding a motorcycle, not stopping/giving way winds me up, I always feel like they haven't seen me but it seems to be intentional most of the time. And bloody mobile phones.
You should share your experiences from traffic in India with @CrispyChrispy above. I've never heard so many car horns at one time.
