make sure your brake switch is adjusted properly. Your brake lights should come one when you barely touch the pedal. It sounds like you have to press a bit more for your lights to come on.

This is something Toyota would be interested in hearing, but they are probably already aware of this as a potential problem. Offhand, I can't think of anything else that would tell the car to stop depressing the accelerator once the brake-applied signal is lost. But I could be forgetting something.

Or you could drive the car yourself, and skip all the inherent problems of cruise control. Never-turned-on cruise control never malfunctions.

Yes, however the never removed from the accelerator pedal foot tends to cramp well within the cruising range of most vehicles.

Also, the cruise-controlled car tends to stay within a narrow range of speeds, which limits the urge that police have to pull you over.

That is most often why I use the cruise. My natural tendency is to at least keep up with other traffic if not to cruise slightly faster than the median speed, which is not good if one is trying to maintain a clean driving record.

Oh, they'll find a reason, Esp. if your licence plate isn't the same colours as theirs.

I didnt pay nearly $40k to have to avoid cruise. That is bullshit

I have never seen a cruise control that didn't do this to some extent.. the one in my Chrysler Laser would accelerate briefly when you put the clutch out.....

This one is pretty aggressive. Doesnt bother me so much, but might drive a little old bluehaired lady nuts.

Wait til you get adaptive cruise control.

I've noticed that fuel economy suffers quite a bit with adaptive cruise control because the system backs off the throttle sooner than I would, and when changing lanes to move around a slower moving vehicle, the radar sees that the obstacle is gone and then reapplies the throttle. The adaptive cruise control seems to adjust the throttle a lot more than I would for about a or 2 MPG penalty over what I get with my right foot.

I guess you would say I already have adaptive cruise control. In the laser mode, it work that way. Sometimes I switch it over to normal because I find some of the adaptive features to be irritating.
