Speaking at a transport committee meeting, assembly member Lady Victoria Borwick said the problem was that TfL suggested a place rather than asking councils whether they wanted a station and if so where the best place would be.
She added that some are located on busy main roads and would be better placed elsewhere.
When Borwick was accused of nimbyism, committee chairwoman Val Shawcross defended her. "One person's nimbyism is another person's local knowledge," she remarked.
TfL managing director of surface transport David Brown explained that docking stations could be moved but that the main inhibiting factor to doing so is cost. The committee's findings are scheduled to be published later this year.
