Yes, that old chestnut...We got this from HQ: Concerning the request to cyclists to dismount as they pass through the barriers, this is a Health & Safety issue, which must be obeyed. I'm tempted to call their bluff and say that other vulnerable road users such as motorcyclists, mopeds and drivers of open-top vehicles should not be allowed to enter via the barrier for the same - as yet - unknown health risk (presumably, being clobbered on the head by the descending barrier). Part of me says go for it. Part of me says why bother? Waddayareckon?
