Tunnel vision

Steve Cropley said the running of a Lotus 88 “twin-chassis” Formula 1 car at the Catesby Tunnel aero testing facility was an ear-splitting event (My Week in Cars, 12 January). I fear it also affected his eyesight, as the car depicted was a Lotus 79 (ground effects) car from three seasons prior. Gareth Tarr
