My wife and I use the Redbridge park-and-ride in Oxford every week and find it excellent.

When we decided to go to London for the day, the obvious choice was to leave the car at the Thornhill park-and-ride and catch the Oxford Tube.

Imagine my reaction when we arrived at 9.30am last Thursday to catch the 10am coach and found the car park full.

The attendants told me: "It's always like this."

I was told there were no overflow arrangements.

All they could suggest was to leave the car on the Sandhills housing estate for the day.

I think this is utterly disgraceful and unacceptable.

What is the council playing at?

Yes, there is still work outstanding, which is taking some car parking spaces, but I doubt very much it would impact that much on the situation.

How can we attract visitors and tourists to the city when a park-and-ride is full before 9.30am? How can we encourage local people to avoid taking vehicles into the city and use park-and-ride when it is full by that time?

How can residents of Sandhills be expected to allow the roads around their properties to be used as an overflow car park?

How come this problem was not foreseen and some alternative overflow arrangements made? I will not use Thornhill again until I am sure this fiasco is sorted.
