How is SCC in traffic?

[tarhoosier]

I love this forum.
There are the mods and go-fast people who "MOAR POWER-R-R-R".
Then those who seek how to make auto hold, auto brake, auto cruise, auto wipers and headlights and so on work for them.
Then the Not applicable, No Response, just here for the ride (me).

Maybe for now.. but it'll eventually suck you in. It already has with your post above! LOL.

If you like following closer, I think 1-2 bars is perfect. If you don't think it reacts fast enough for braking, then use the "fast" response time in the gauge cluster settings. If it brakes too hard, setting the distance higher or the response faster may help. It'll never be chauffeur smooth brakes though. If it has a hard time reacting to merges, higher distance and faster response as well.

For me, my commute has stretches of 60-80 MPH and then sudden gridlocks to stop, and then crawls from 3-20 MPH. 2 bars with fast response was working fine, until one of the full speed to 0 stops almost made me crash. The car seemed to me to detect the slow down too late and was slowing down too slowly for comfort, and I ended up overriding the cruise and braking on my own. So I won't know if it would've been fine lol. Now I have it set to 3 bars with normal response.

Overall, the cruise control works great. In my opinion, with the right configurations, it accelerates and maintains distance better than I expected. I just wish it detected merges better.

Ah see, I keep it set to 1-2 to stop those idiots from cutting me off for no reason. I couldn't discern much difference between those modes, but I'll have to try again. I assumed they were measured car lengths.

So following up: @Mr. Incredible , those settings worked perfectly! Soooooo much more comfortable and smooth at 3 bars instead of 2 bars. Considering traffic is the only time I would consider using SCC, this is a game changer. Thanks!

Also played around with fast vs standard reaction time. I prefer fast

Im gonna have to try 3 bars as well. With the reaction time, do you find that fast means that it brakes you more quickly or more slowly than the standard or slow setting?

Largely the opposite actually. It just feels like it gets moving more quickly than standard. To me, standard feels like it lulls/crawls a bit before actually adding throttle. I thought I noticed the car brake a bit sooner but I felt that there was a slight discrepancy in the way traffic was moving and chalked it up to that. I have only used it once since the post from a week ago, so I still want to do some more experimenting. Likely later today, stay tuned

I agree, and get you moving a little quicker. Of course if you have the distance it to be short you’re going to be seeing a lot of braking in stop and go traffic.

Which was my biggest issue because it would brake pretty damn hard due to the short follow time/distance. I take it as a given that SCC will never be as efficient on gas or brakes as my driving (if I try, at least), but being jerked around by hard accels/stops was something that I couldn't look past.

Sure. Just ease up on the distance.
Even If somebody cuts in front of you it won’t be so bad.

I had a car cut across me this morning, I was in center lane set at 45, Fast, and two bars, and the other car cut from the right lane to the left lane, maybe 1.5 car lengths in front of me.

Let's just say I'm glad I had put my coffee down before that happened.

I realize I drive a G80 but I think these things all behave about the same way.

Ok just did some testing on my way home. No idea what kind of drivers you guys have around you but...started on 3 bars, fast reaction. Holy spacing Batman, I was what felt like 10 car lengths and people kept jumping into my lane. Move it to 2 bars, it’s still following too far and now people are not only jumping in my lane but the cruise is having to constantly brake me further back. I don’t know, 1 bar seems to be the only one I can do that doesn’t cause people to jump in front of me. I am however liking the fast reaction time a bit better but more testing is needed

why does it matter if they jump in front of you? if you have a lot of space the system will have no issue reacting, it will slow without hard braking when I sees the car.

3 second rule is what I follow, which means at 65mph there is at least 7 car lengths between you and the car in front of you, yeah that is a big distance but in an emergency stop situation you will be the guy that doesn't rear end the pack in front of you.

3 bars seems to be 3-4 seconds and it is perfect for my driving habits. I don't care if someone jumps in front of me when there is enough of a gap to accommodate them, it pisses me off when there isn't that space and they do it, which is what 1-2 bars creates IMO, people think there is space and they force their way in forcing you to brake hard.

Are you consistently driving in the left lane?

 

[joschneider]

Are you consistently driving in the left lane?

Yes, which is why I don’t like a long follow distance since it’s the passing lane. I set my cruise for 75 which means I’m passing 90% of the traffic on the freeway and I’m constantly moving back out of the way for faster traffic. I guess my use case isn’t good for SCC, I imagine if I stayed in the middle lane and just chilled at one speed I wouldn’t have this issue. #fastdriverproblems

Seems like you have the same gripes as me with SCC. I wouldn't bother using it at those speeds because it leaves a mile of gap, but it is useful in bumper to bumper slow traffic (now that I know the 3 bar thing). If traffic is moving at a decent rate, I want full control so I can pass people

The whole ___ seconds thing is a guideline, not a rule. Depending on your level of attention, reaction time, and the vehicle you have, you'll have a different number. I highly doubt the person who made that suggestion drove a sports car with massive brakes

The 3 second rule is what my dad taught me, and in the last 20 years braking distances have come way down, totally agreed. Of course that doesn’t mean we are tailgating, just to get ahead of that yea me and you might be better off using it for long road trips or true bumper to bumper crawling traffic

So many variables from day to day with speed, closeness, and idiots behind the wheel. I've used it on trip where I could go 100 miles and never touch anything but other traffic situations it is pretty much unusable. You also have no control over the guy in the next lane that wants to be in front of you. Most times I use 2, sometimes 3 bars. Sometimes everyone is close, other times more safely spread out

Its a computer and it sees the car in front of you. It does not see the brake lights that you see on the cars 8 in front of you that makes you take your foot off the gas. It just won't be as good as an experienced driver. But it sure can be great most of the time and make tedious traffic much more bearable.

Would be nice if it would adjust your speed when a car cuts in front and project a single digit hologram on his windshield.
