roundabout from troon to monkton, some big fecker with oakleys on decides he wants my lane, emergency braking session avoided going into driver side rear door, get round the rest of roundabout and he pulls into left hand lane, go by him having a stare, he starts gesturing at me and then floors it up behind me, then goes to undertake me then back on my tail, waited until next roundabout at prestwick airport and floor it away, all fine until stopped at lights in prestwick and suddenly bloke thumping passenger window, looked in rear mirror and the audi is a few cars back and this is his passenger! decided best to call hawaii 5'0 as was getting a tad scary, told by cops to head to ayr police station and while near there audi appears where it opens up to 2 lanes near retail park where dominos etc, hear sirens and a cop car has appeared which pulls him over! went in and seen cops, seems it was a american tourist who just picked up the audi earlier, accused me of trying to "grab his lane"...no charges but given a watch his driving for rest of stay warning
