Oh I don't know about that. They say you can live without a spleen.

I use cruise on roadtrips sometimes and at other times I don't. What drives me crazy when using cruise are "cruise control races" and my awareness of the inconsistent speed of many other drivers---you start to pass them and they creep up in speed. So you pull in behind them and then they slow down again and then you're coming around on their left again and then they increase their speed again......you guys know the story. This doesn't happen as often when one is driving....what....manually?

The notion of trusting to adaptive cruise control in heavy urban expressway traffic is frightening. I can see it being most useful in rural areas.

I don't like it and rarely use it. I don't feel like I am in control.

Totally agree with you!! This behavior makes me crazy! I'm honestly still trying to figure out if it's REALLY that they're THAT inconistent with their speed...or or they're just being jerks by having the "you're not passing me" attitude. I don't know, maybe it's a little of both!?

Most cars I've had didn't have a "tap down" feature, just "coast" - where if you hold the button down it would decelerate but once you let go it would return to whatever speed it was set at. I can't think of exactly which car it was, but I also recall having at least one where hitting the gas pedal would disable cruise.

My mother bought a used VW Passat for real cheap last year (think it's a '99) and the cruise control is broken too, amongst lots of other things LOL. Great to drive but it's got more electrical problems than any car I've ever seen... and I've owned early 70s British and German cars.

I had never thought about that. Next time I need to buy a wonderful used car really cheap, I'll look for somebody dying to get rid of a car because the cruise control doesn't work. It would be a real bonanza if the radio doesn't work, either.

The old joke is "Volkswagen: now standard with broken cruise control!" Volkswagen has a fascination with using vacuum switches where electronic switches would do the trick just fine. That's why the electronic locks on Volkswagens engage so slowly -- they're vacuum-actuated instead of electromatically actuated like the rest of the automotive world does it.

Same for their cruise control system -- it's vacuum-operated, and if there's a leak anywhere in the system the cruise control won't engage. Usually if a Volkswagen's cruise control doesn't work, it means one of the pedal switches won't completely seal any more. Unfortunately that's not the problem with mine. I wish it was since the vacuum switches are relatively cheap to fix. With mine it's a faulty wheel speed sensor, which would cost me almost 4 times as much to fix if I were inclined to actually fix it. But at 155K and a total vehicle value of around $1,500, it's just not worth the money, especially when I have 2 other cars that are more comfortable to drive and have all their systems functioning properly.

As for "coast" versus "tap-down," the "coast" feature essentially is tap-down. Tap it once and it will drop your speed 1 to 2 miles per hour. At least that's how it has worked with every cruise-control-equipped car I've had with a "coast" feature. The Volkswagen is the only car I've ever had with cruise but without a "coast" feature. The whole cruise control apparatus on that car is truly annoying.
