There is a stretch of road in Ayrshire where motorists will find special warning signs and meet cars apparantly coasting uphill backwards as baffled drivers are confused by their senses. Electric Brae, on the A719, nine miles (14km) south of Ayr and 13 miles (21km) north of Girvan, is just one of many such anomalous spots in the British Isles. The road crosses the side of a steep valley and is actually rising slightly, while appearing to fall towards a stream.

Magnetic Hill, between Ballabeg and the Round Table on the Isle of Man, is another surreal slope. Local wags say that the odd effects are not down to magnetism, but the Little People coming out to push the cars uphill.
