Sir – Arriving at 9.15 to catch a bus to London the car park at Thornhill park-and-ride is, as usual, full.

We, like dozens of others, parked on a muddy verge/kerbside despite warnings not to. When is the council going to provide: a) More parking in total — the next door landowner may be happy to sell another field b) Separate out those parking for work in Oxford from those trying to get to London, Heathrow or Gatwick?

Because parking at the hospitals or in town is so expensive, hundreds of workers are using this free facility which is fine for them, but becoming very difficult for anyone hoping to get to the airport on time.

What plans are there for improvement and if there are none then it is time to make plans.
