Much is made by learner drivers and others of the supposed dangers of the hamburger' roundabout at Headington, Oxford (Oxford Mail, October 24 and 29).

If you ignore the emotionally charged rhetoric, consider the following factual problems: 1. You risk an accident every time you try to get out of Barton and head in any direction other than left. Who designs a complicated roundabout, costing millions, then totally ignores a complete estate situated next to it, by not including traffic lights for a safe exit?

2. On ordinary roundabouts, added traffic lights occasionally develop faults and cease to operate for short periods. Not normally a problem - you just give way to the right.

The traffic through the centre' design, however, becomes an accident waiting to happen.

Motorists have tried to drive the wrong way through the centre.

So who is going to stick their head above the parapet and give an answer to these flaws?

How are they to be corrected?

It would be interesting to see a court's reaction to a case brought for negligent design, based on flawed or non-existent risk analysis.
