SIR: I really do not see that technology is an issue for stopping cars using the Hundred at controlled times. Many car parks now have automatic number plate recognition systems to record cars entering. A similar system could record anybody driving down the Hundred between 10am and 4pm and issue a fixed penalty notice, just like an overstay in a car park.

Indeed, I have no doubt one of the large car park operating companies would be delighted to do it for us at zero cost if they could keep the monies raised.
