GUYS, I've been in an accident at the exact same place (in front of Flamingo heading to MElawati), I couldn't brake in time so banged into a Waja. My mom's Iswara really bad, cannot jalan, cost insurance co. RM 6000.
Anyway, MRR2 is a very dangerous highway, sharp bends, heavy bumps and uneven surfaces and tilted as well. But extremely useful and free.
Just be careful, I drive on average 60km DAILY on MRR2, so I try to be careful. Definitely no speeding.
Some of the bumps on MRR2 will send you FLYING! at 120kmh. Even in Volvo 240 aka Brick aka Tank (happened to me once, lucky didn't accident).
