Sir — I can't see how the pedestrianisation of virtually all the central streets will work, but then I'm not on the same intellectual level as the geniuses who designed Frideswide's Square.

Normally one might expect planners to first work out if something is feasible, then decide, if it is, whether it is a good thing for all who use the city.

It seems, unless they are playing their cards close to their chest, that first they have decided it would be a good thing, which must be debatable, then they are hoping for inspiration, like a new through street to appear from nowhere eg Christ Church Meadow.

Why debatable? Because inevitably people will have to walk further from and to bus stops, taxi costs must soar and essential driving, eg to hotels, students arriving and leaving, will be a nightmare.

The centre could become sterile. Pleasant as the artist's depictions are, one looks in vain for emergency vehicles, security vans, builders lorries, delivery vehicles, baffled drivers, signage, drop-outs, kebab vans, and of course illegal cyclists and hawkers.

Where is the pressure coming from? High Street colleges that were prominent in banning cars, failing to realise that buses make far more noise than cars?

The only people who could not see that Frideswide Square was a unnecessary muddle, were the same people planning this scheme. Now they propose to sink more of our money into its re-design, and doubtless thousands more into planning their new idea.
