WITH reference to G Parr's reply to my letter concerning the dumping of rubbish out of vehicles at speed. Motorbikes, Mr Parr, motorbikes.

One should never use a 'shove-iron' on a motorway. It is illegal.

Further, anyone who can pedal a push-bike at 70mph on the flat should be signing up for the Tour de France, they'd win hands down.
