Otherwise, the system will apply brakes as the primary means of avoiding a frontal or sideswipe crash (it will not swerve from the vehicle's lane as long as it can detect lane markings on either side). If anyone thinks they are smarter, have better reaction times and superior hand-eye coordination, sure, please turn the ADAS off. and ADAS only forces the car to follow these - so it will initiate braking when the CAS is violated, both frontally and laterally. We tend not to follow the basic commandments of driving. In KL, I use it only for a few minutes to relieve my right foot for a while.ĪDAS is just its third word in the acronym - ASSIST. The only time I enjoyed ACC was outside KL on the national highways of TN. To the contrary, I find myself being more vigilant than normal while using it. Having to do all these, takes away the relaxation you expect to get from ACC. This may be partially mitigated in newer cars with lane change assist that can read lane markers. This catches you off guard and you are forced to press the brake, which de-activates the system. It perceives the road ahead to be clear and rapidly accelerates to 60 hurtling you towards the outer edge of the curve. At the crest of a curve on the road, the car ahead goes out of range of the radar. Imagine that at a set speed of 60 you are following a car at 40. Especially where I live now, the roads are all winding and change their elevation rapidly. In this scenario, we would use our judgement and adjust our speeds slightly to allow for error and then overtake.Īnother scenario: If there is a bike ahead riding on the lane marker, the ACC perceives it to be riding in the lane, you will have to switch to the high speed lane to continue at that speed or manually override the system by pressing the accelerator slightly.Īnother scenario : Very rarely will you see straight roads in Kerala. If the car ahead so much as slightly veers towards the fast lane, it will stop accelerating. You indicate to the fast lane, once in that lane, your car starts accelerating back to 80, but it catches another car or bike ahead on its' radar thats' travelling on the same lane slower, it will then stop accelerating. But I found it still too much of a hassle.Īnother scenario: You are travelling at 80, you approach another vehicle travelling at 60 and it slows down. I tried mitigating this by manually in such scenarios, by reducing the speed via the steering ACC controls and then setting it back up. Now imagine this happening every few minutes. It will then take a few seconds before it decides everything is ok and accelerates back to that speed. A car or bus in the third (fast) lane carelessly straddles the second and third lane while it overtakes you, your car will brake to slow down. One scenario : Imagine you are driving at 80, in the second lane, and following another car at the same speed. Can you elaborate on why you find ACC to be not so useful? First, thanks for your detailed perspective on ADAS.
