Re: Oxford has it right
"In two town centre streets, you have to walk bicycles between 1000 and 1800. Outside those hours you can ride down those streets."
Good idea. The same should be the default for bus lanes too. Many places have bus lanes with "active hours", sometimes only in certain directions in mornings and afternoon/evenings, ie in or out of town. Around here, they are all 24/7. Probably because someone said they had to have bus lanes but couldn't be arsed to spend the time and money on where and when they were most needed.
