That mobility bus always causes chaos! I don't envy the driver.

I agree that it's an issue - I've also had horns and swearing, to the point of near fisticuffs. However, I've thought about it quite a lot, and I'm not sure I'd want to change to one-way. I think that this would lead to the road becoming a real rat-run for commuters (either N>S or S>N depending on the outcome), and that average speeds would increase because cars know they don't need to look for cars coming the other way. I am happy to put up with a bit of beeping here and there if it means that most people steer clear of Devonshire because they know it's a roadblock! Any changes could have side effects.
