Self braking has helped me already... it wouldn't have been a serious crash, but the car managed to react faster than I did. That is no surprise... humans have a very slow reaction time, the only advantage humans have is being able to see more/understand more and predict what is going to happen. However there are situations where you can't predict. That's where the computer helps.

Also the adaptive cruise control helps me save fuel and drive more consistent.

Lane assist has saved me a couple of times (keep in mind that I do sometimes drive 1500 km a day, and that it often is not possible to find a place to rest for 20, 30 minutes, sometimes even hours as lorry drivers are forced to rest at night here, and all car parks are completely blocked by lorries). There's no way I'd want to drive without it anymore. (And no, I don't drive any different from when I didn't have those assistants, guess I was lucky (and drove less back then). Also if I am this tired, I'll try to rest ASAP.
Never tried that, though I'd expect understeer. I think It'd corner better than a car without stability control though.

嘉伟哥 ah

Not every day. But usually 4 times a year I do. Every day I drive 190 km... in the morning 85, in the evening after a long work day another 85.

I can drive properly without the safety features, and I don't drive differently. I have caught the car last minute before I had the safety tech. Maybe it's just me, but sometimes I nap away even though I'm fully awake just minutes earlier, and can't even sleep if I try to. I try not to rely on the safety tech, cause I know there can be a road section without markings, there can be dirt in front of the camera, or really heavy rain/fog can disturb the system too... . But so far this tech has worked almost always (there's also a little icon telling me when it sees road markings). Even if you only ever need it once, you'll be glad that you've had it when that time comes.

And what the reviewer is saying is what I am trying to say, too. I'd like to add that you never know when you may need it. You may be the best, safest, most attentive driver in the world. But at some point you may get distracted, you may be a bit tired and can't find a place to stop/don't realize you're getting tired. Something completely surprising and unexpected can happen... remember the poor cop that had something drop from a lorry in front of him? How can you predict that happening? The computer would slam the brakes much faster than a surprised human being can.

Btw., we do have reached the point where some self driving cars are safer drivers than humans. Tesla is there for example, and Google is years ahead of Tesla.

Oh, and I'd like to know: When you change lanes, do you turn your head to the side to see if there's a car in the blind spot?
