When did you last look UNDER your car? Not suggesting you may find a bomb or incendary device, but there could be rubbish. I followed a car today that looked as though it had half a tree and a few hundred yards of cable hanging from the underside. It is not an unusual sight, along with the common hanging exhaust and plastic bags.
It is my habit of checking at least each week for any debris or signs of damage to brake lines, cables, inside edge of tyres, and the rest of the undercar impedimenta. Fortunately I have never yet found a dead cat or other animal!
