Seeing that bikes attract a brief mention, and wild rides, try riding a Husqvarna 500 Automatic, fitted with nobbly tyres on the road at 140 -150kms/hour and experience the handlebars going from side to side yet the bike still tracks straight and true - now, that is an experience and it's happened to me - or another time, riding my Montesa 360GP on a stretch of country road (no street lights) and the back wheel locks up with a seized engine - inspection of the tyre skid marks (not MINE !) next day revealed a straight and true black tyre strip the length of one hundred feet. More about 'a' or 'the' Bentley next post. Regards Styria
