Hi, I have been cycling to work 2/3 days a week since March. Generally goes alright, but there have been 3 times when drivers have not stopped at roundabouts for me and nearly knocked me off. I wear high viz vest, backpack cover, hi viz tape on bike and leave my flashing LED light on but I appear to be invisible to them! Im getting concerned about it now and dont know what the solution is beside getting off and crossing on the footpaths? Any suggestions how to be more visible at roundabouts so that they stop for you? thanks, JD.
