The issue is other people. We went, in the Caterham, to the Goodwood breakfast on this day (2008 or 2009 can't remember) as shown below (these cars were parked on the main straight). It was sunny and dry when we left.
On the hill on the way back there were lunatics coming down the hill who had no idea what they were doing - a woman in a Skoda ploughed diagonally across the road simply by driving at 20mph when she should have been doing 3mph. Fortunately we had slid the Caterham sidesways into a gate opening a few minutes earlier otherwise we would have been wiped out.
