With the jam inevitable on this long weekend, let's see how the SMRT MAN buses hold up to the cross border demands and tight turns, speed limiters being locked at a higher speed for Malaysia regulations and how comfortable the passengers will be getting stuck in a Causeway jam on it :P. Not to mention the striking "Lion hair" Lion's City Hybrid bodywork design travelling to and fro the Causeway.
