Sg long's traffic condition is depend. Sometimes it will jam like hell; of course sometime will smooth like hell also.
Like today, no idea why it jam? I believe is because of the traffic light near the Petronas station there.

For BMC, confirmed will jam unless we having police traffic command the traffic then its better.

So... i can say depend on you whether can stand still to this kind of traffic condition or not. Mine is fine because i'm motorcyclist.
