Whoops Sorry
If that's 25% then 50% will pop my eyes out the socket.

Yeah, I agree, that 25% sure feels like much more.

Re: No longer sure if I trust ACC

From my motorcycle riding days I've learned to never ride behind or ahead of someone for long, just too dangerous... Now there's another reason on my list.

-Stupid drivers... check.
-Deer... check
-stupid cars... new check.

Re: No longer sure if I trust ACC

I know the FCW doesn't apply the brakes, and only alerts you, but I had the ACC set so it alerted me as well as applying the brakes at partial force. Since I posted, I've still been using the ACC and it works just like it always did, but I've got my feet much closer to the pedals just in case. In normal around-town driving, I've had just the FCW go off when a vehicle cut across in front of me at a similar distance. I'm assuming the bag was somehow inflated just enough by the wind for the sensor to recognize an object, and it floated directly across the lane, so the motion must have alerted the sensor.

I don't think ACC is a foolproof system at all, just a convenient aid in certain driving situations. On my daily commute, about 20 miles each direction, 99% highway, I probably turn the system on and off about 5 times in one trip, because I'm used to the way it reacts and I've learned what situations confuse it, and anticipate them.

As far as the system braking when a car is exiting but not fully in the exit lane, mine does the same thing. It makes you look like an idiot to fellow motorists, but the car is just waiting until the lane is completely clear before accelerating. Not ideal, but imagine the trouble they'd get into with a car accelerating before the lane is clear!

When I first got the car, I would usually use distance 2 or 3 (tailgaters are one of my pet peeves), until I realized that any distance greater than 1 is an invitation for people to cut you off.

Finally, the Rover behind me was a nice Sport Autobiography, so I do believe it was equipped with ACC. Being a Rover, I'm sure there was a wiring issue and it wasn't working at all. Another reason I'm glad I drive the American Range Rover, even if it does occasionally think I'm about to have a major collision with a grocery bag

Re: No longer sure if I trust ACC

When the ACC applies braking do your brake lights come on?

The problem with "foolproof" systems is that, as soon as one is developed, someone else goes and makes a better fool.



The FCW and ACC systems are meant to be AIDS to an alert driver. Don't be a passenger who just happens to be sitting behind the steering wheel! Be in control of your vehicle and aware of your surroundings!

That's the problem with these technologies - they encourage people not to pay attention since there's something else doing that for them. Like welfare. Take away all the technology and weld a sharp spike near the driver's head. I'll bet there are a lot fewer accidents. There are of course the times that the system works and prevents an actual, otherwise unavoidable occurance. But those situations usually become the exception rather than the rule.

Each little step is one closer to human control of a vehicle being illegal, since everything will be automated. Extreme viewpoint I know, but only in how far into the future you have to look.

Re: No longer sure if I trust ACC

At least there will always be race tracks and off road trails for real car enthusiasts.

I just rented a ford escape last week. Nice car, nice little turbo engine (except like my last turbo engine it smells of oil when you turn it off)... The down side, the electronics: every time I was speeding it would alert me, and there was an 80mph max on the car. Personally, I think that's poor business practice to offer a car that can't go as fast as traffic or a stock version on a dealer's lot without telling the customer. I was overall impressed with the little thing though, even though I high-sided it in a snowy driveway with ease... Did I mention modern "AWD" cars that have no way to override the TC are totally useless? Basically all FWD based "AWD" cars I've driven are so useless in real traction situations because they cut power when a wheel slips. They're FWD until you need AWD, then they're dead in the water. Antoher example of electronics making life oh so much better...
