Advanced cruise controls

Does anyone have a car of any make with features like adaptive cruise control, auto stop, or lane departure? What has been your experience? Are these useful features? Do you find that they misfire often enough that you turn them off?

For S / S in general, some complain that starts are rough but I'm betting this is more common with a 4 cylinder due to more time between compression strokes.

I'm more interested in the autopilot controls, automatic braking and adaptive cruise.

I once owned a 2012 Genesis with Automatic Distance cruise control and while it worked well, adjusting speed to maintain a driver pre-set following distance, I did encounter a problem that caused me not to use it too often. I was following traffic in the middle lane on a 3-lane highway at about 65 mph with the cruise control set. A car suddenly cut in front of me from the left lane and my car went into an automatic emergency brake mode. The sensors had suddenly detected a rapid change in the distance to the car in front and braked hard to regain the set distance. The car following me had to take evasive action to avoid hitting me. While the car that moved in front of me had certainly 'invaded my space' it was not so close that it would normally have caused me to brake.

I own two cars with these systems - one Subaru and one Chrysler. I like the forward collision warning/automatic braking/adaptive cruise on both. Have had very few false alarms on the collision warning, mostly when i coast up too close behind a car turning right. I don’t drive with cruise too much, but do find the ACC is useful on long trips as it helps reduce driver fatigue. I find it most useful in both cars for stop and go backups on the freeway, both cars will just tail along 50 feet behind the vehicle in front from 0 up to the set speed. I have had the situation described by Dervman above occur. The Sube handles this OK, the Chrysler brakes a bit hard then accelerates pretty hard. I hit the cancel button when someone cuts in. The jerks do tend to cut in front of you when using ACC because it maintains reasonable following distances.

I find lane keeping almost totally useless. It’s almost always wrong when it kicks the wheel because it has misread the lane stripes. The Subaru has only on/off and I never use it, it is far more annoying than useful. It’s much better on the Chrysler, which has adjustments for both sensitivity and how much torque it applies to the steering wheel. The Subaru kicks the steering wheel in your hands as soon as you get off center in the lane (as when passing a semi), whereas the Chrysler gives more latitude and just starts gently pushing back. Not sure it’s all that useful, but at least it’s not annoying.

The Chrysler has auto stop. Mostly it never triggers, but I haven’t had any problems with it and it doesn’t bother me when it does.

I'm looking at a BMW and I'm considering their Driver Assist+ system. Trying to figure out whether it's a good thing or if it'll just be a waste because it mostly gets switched off.

I'd call the Chrysler system better as a driver assist / warning, kind of like a stick shaker in a jet liner. The Subaru seems more like a way to save drivers that are non participants.

However, any of these systems just encourage inattentive / texting drivers and I'm waiting for the law suits when someone gets into a non assist car and crashes thinking that tech , that isn't there , will save them.

I don't want tech doing too much for me unless I ask it to. An example is the program Word that puts in 2x spacing , indents and all sorts of other automatic stuff I don't want. Sure it might be useful for someone that constantly uses it but for the occasional user, it is just a hassle.

And for the record, push button start if a really bad idea. The ignition key is tactile and easily manipulated in an emergency shut down situation. This rates up there with touch screen radio / HVAC. Bob Lutz ( Of Chrysler / GM fame ) has frequently said that a radio needs a knob for volume and one for tuning. The HVAC should have a separate knob ( lever ) for temperature , blower speed and where the air comes out. . .

That really depends on how you drive and where you drive, so I canít really say. On the Chrysler it was a no brainer. The system cost $1k and includes many other useful functions such as a 360 camera system and front and rear parking sensors.

Yes, well we're all 20th century dinosaurs here. I'm trying to figure out what the experience has been with the new stuff.
