I inadvertently discovered one way of dealing with tailgaters, back in the days when I was honing my engineering skills on a series of geriatric Minis.

A perennial problem with the sideways engine was oil surge: on right-hand bends, the oil would slosh to the end away from the oil pump, and if it was below the recommended level (not unknown in old cars) you lost oil pressure. On this particular occasion I went round a sharp right-hander and the oil light came on. No problem: shove her in neutral, switch off, coast for a few seconds, switch on again and bump start. This last resulted in a short sharp deceleration - without brake lights - before the engine fired and normal operation was resumed. The driver behind backed off rather quickly.
