Lunatic driver, tailgated me for several miles in heavy traffic A1M and then undertook and pulled in front of me too quickly - causing me to brake - then proceeded to "tap" his brakes - not content with doing it to me did it to car in front too. Young driver - white van - say no more.
Pulled out of a side onto the main road I was cycling along, who was cycling, and I suspect deliberately veered towards me, forcing me to take to the pavement, so I wasn't side-swiped. Friend in passenger seat stared at me blankly, as if to suggest disappointment that his friend had not forced me off the road.
Very aggressive towards cyclists, beware and report.
