Since either the late 80’s or early 90s we have been using ShuRoos on our cars.

The real test: south of St George heading to the border doing 110kph, a family of 5 grays jumped through the hedge into the north bound lane in line to be hit and I thought “poor animals, poor truck!”. The moment their feet hit the tarmac, they scattered north south and west and none got hit.

Those whistling things couldn’t do it and for a price less than the insurance excess yet alone the inconvenience of an accident - why wouldn’t you buy a ShuRoo?
