For the record, this was Formula One Simulator.
"Mastertronic (unwittingly hilariously) included this little gem in the instructions:
'Steering wheel - Use a sellotape tin or similar object, about 4 1/2" indiameter and 1" deep, hold it at the top and position it at the centre of top row of keys so that it nestles against the ridge at the back. Roll it to theleft or right with moderate pressure to steer. To begin with, a rocking motion on the wheel may help get the feel of the car.' - Priceless!"
