Yes it's too slow. My driver was caught overspeeding at SLEX at 112kph. Seriously! If we known we would be caught, we should just drove at 140kph! For me, the best limit is 120kph because not all cars will be driving at 120kph anyways and this should be legal on overtaking lanes. How can you overtake with the same freakin speed? Accidents occur mostly during sudden braking and it won't save you even if your speed is 100kph, but this is a different issue.
