Rubbish Yorkie,very dangerous a bus useing all 4 lanes and don;t forget it has to swing from the inside lane,a crazy manouvre by any standards.
You are talking through your hat, Wrex! What are the breaks in the central reservation for, but anything other than traffic to change their direction of travel. By you analogy it is dangerous for any vehicle to use the gaps, lorries, bread vans, decorator's vans with ladders on board or indeed any long vehicle! Get a life, man!
If it was considered dangerous the road would be full of signs prohibiting the manouver.
Norman08, the reason for the number is that they run every 10 minutes and drivers need a break.
Find, something less stupid to complain about, and instead of moaning and groaning on this Forum all the time, get off your ass and DO SOMETHING ABOUT IT!
