I would be very surprised if Sainsburys' manager gave permission, as that could make him/them liable for any damage.
When my son was starting off, we began in Harvard Road alongside the A4, where the CPZ and the residents off-road parking meant there were few parked cars, and there is little moving traffic, and did the basic clutch control, steering and applying of the brakes, including emergency stopping, there. We then moved on to the circuit around Duke's Meadows to practice handling a moving car, using the area by the allotments to practice three-point turns and reversing into parking spaces. |
