Hand gestures (looked like they were wanking off a mouse to be honest... Probably indicative of the driver's pride and joy or lack thereof...) from both driver and passenger seemingly for not giving them right of way for an obstacle on their side of the road (incredibly inconvenient and possibly dangerous for me to stop due to 60mph speed limit and just after blind bend). Driver looked like a nasty piece of work and driving was indicative of that also. Avoid at all costs.
Missed his turn off and instead of doing the sensible thing of going to the next exit, he/she indicated once and then cut me off, forcing me to jump on the breaks.
A great driver. Courteous, careful, considerate, civil. A+
