Worst, in a “this is the end” fashion would be the current one. It’s RWD and fairly rapid, but I certainly wasn’t driving like a loon. Heading up to Aberdeen, bit of fog but nothing untoward, and then whiteout just past Montrose. Conditions changed from damp road to couple of inches of snow in about 200 metres. I was pottering along at about 45-50 mph, hit the snow, and then spent the next 1/4 mile snaking along the dual carriageway hoping the lorries and cars behind were going to be able to a) stop before they hit me, and b) pull me out of the verge once I came to a halt. Somehow managed to save it, parked up in the hard shoulder and sat it out.
I’ve got the train to Aberdeen ever since.
