Doubtless petrolheads will be familiar with Jalan Ulu Yam – the fast, twisty road is a favourite of enthusiasts on both two and four wheels, who enjoy a quick blast through the corners, usually on a Sunday morning. It’s also extremely treacherous, especially at night, where many stretches are unlit.

The right-hander just before the intersection to the town of Ulu Yam Bharu, which you’ll see in the video above, is particularly dangerous – it comes after a fairly straight stretch where drivers can get up to speed, and although the corner is lit up, it’s rather dim and the way it tightens before reaching the junction quite often isn’t immediately apparent until it’s too late.

As you can see, the driver of the Proton Suprima S in the video appears to be carrying a lot of speed into the turn and does not slow down enough, and as the car loses grip, the rear washes wide and threatens to pitch into unrecoverable oversteer. On the tight two-lane bridge with a car on one side and a barrier on the other, this could have spelt disaster.

Thankfully, the Suprima S’ stability control – which comes equipped on all but the base Standard variant – seems to step in at exactly the right time. Looking at the video closely, you can actually see two places where the loss of control could have been catastrophic and where an unseen helping hand appears to stabilise the car’s movement.

The first part is when the rear slides onto the sandy road shoulder, where the car might have continued oversteering and hit the barrier, or spun and crashed into the oncoming car. Here, ESC brakes the outside front wheel to quell the slide, bringing the car into a stable position before anything untoward could happen.

Next, the driver could have overcorrected the slide by countersteering while also braking for the intersection; such violent changes in input might have swung the car the other way – commonly known as fishtailing – and cause it to careen into the barrier. When it senses that this could happen, the safety net slows down the front right wheel, again to stabilise the car.

In both instances, the lack of ESC could have caused the Proton to crash into the oncoming car, or worse, plow through the barrier and into the river below. The stability control worked overtime to make sure that none of those instances happened and, soiled underpants aside, both the occupants and the car made it through in one piece.

Through watching the video, you’ll see why we champion the safety net as hard as we do. The message here is clear – when purchasing your next car, make sure it comes fitted with stability control. Your life could very well depend on it.

But there’s one more lesson to be learnt. Stability control, as much of a lifesaver it can be, can’t bend physics to save you from absolutely reckless driving. So whenever it is you’re on the road, whether you are on a fast, wide, well-marked and well-lit highway, or on a difficult winding road with little to no illumination – even if you’ve memorised the route a million times – drive safe and keep speeds down to a sane level.
