Yeah you will come across some right idiots at times. In the past couple of weeks I've had a car overtaking me near the top of a railway bridge. It is double white lines and 30 limit as only two vehicles wide.
The car that suddenly appeared coming the other way was not happy. And the crazy thing is, a few hundred yards on it was a two lane carriageway on our side. If he had just wanted 30 seconds more.
The other was a crazy guy in a new mustang. I was following a car in front leaving a good distance as the road was wet. It's a 30mph road and the mustang flies past me. Pulling in behind the car in front. What he didn't overtake both of us I will never know.
Then for the next couple of miles, he was falling back. Then accelerating hard, then braking at the last minute, before starting all over again.
After a couple of miles of this the car in front pulled over into the bus lane to let him past. Sometimes that's the best option.
