[QUOTE="Schwepps, post: 165115, member: 3592"] Positive camber, 3er. A curve should have positive camber built in, and the sharper and longer it is, the more positive it should be. Then the steering should feel neutral as you go round. In a level (neutral) curve, you may have to push on the steering wheel a bit to maintain the same line. In an off-camber (negative) curve, a much stronger push on the steering will be needed to hold the line. The next time you guys do the Semantan curve, try holding your entry speed all the way around. You'll notice that you have to push harder and harder on the steering wheel the further round you go. Indeed you'll even have to turn it more and more. That's a reducing-radius curve with insufficient positive camber. A lethal off-camber curve is the 90 degree right just after the traffic lights going from Bkt Kiara onto Jln Damansara heading towards PJ. Just after the apex, the road slopes off into the armco. Once a young man in front of me did some fancy weaving to make his way to the front of the queue and at the lights did a smart turn at about 50kmh. He hit the apex, his rear-end lifted and he slid on the off-camber into the armco. Too embarrassed by his SIW to stop, he sped off. He only stopped after the Phileo toll to inspect the damage to his left rear side. Appreciate your words on pushing cars on public streets, KL2DC. In most instances, these "dunno what hit them" prangs are the driver's own fault. But some of these road engineering difficiencies are also unfair to less experienced drivers in less capable cars too. And yes, thinice, which great road engineer decided it would be better to use interlocking pavers in the Semantan curve? Those are meant for decoration, not heavy-use highways, and they're actually slippery when wet. Even concrete is not the standard on curved ramps. The standard is rough tarmac (forget the name) with raised yellow stripes laid in reducing spacings to slow drivers down. But some clever engineer thought home driveway pavers would be better and an even cleverer engineer approved it. Gaaaaah!! [/QUOTE]
