"In Columbia, where it happens, it is in the context that some people are very nervous about cycling in the city centre with all the traffic," she said.

"Perhaps the idea could be tried in Bristol as a bit of an experiment.

"I wasn't putting it forward as a formal proposal, but I thought it was something that was worth looking at.... (full story)
