you need running shoes on for this

when a car pulls up anywhere ask the driver if he has looked at the nearside car rear wheel.
Let him/her get out and examine it and then say have you seen it? pointing to it

He/she would say something like" what or no".

So you say it is that round metal thing with rubber around the outside.

THEN RUN LIKE HELL

When l was young and a bit silly, l used to wave down drivers in Reliant Robins in car parks. Point at the wheels and mouth or say, ‘You’ve lost a wheel’.

Er, ok.

Re: you need running shoes on for this

Driving back from Italy one summer in our LHD Renault 5, V was driving and I was reading a newspaper. Pulled up at a set of traffic lights and someone pulls up in the RH lane. Passenger wound the window down and said, "Where's your steering wheel?" I said, "I got fed up with driving so I passed it over to her". The look of shear horror on his face was a golden moment.
