Just made a 600 mile trip, mostly on I-10, and even in moderate traffic with the closest following distance I find the ACC unusable.
The ACC leaves just enough space for some ******* to rush up the right lane and squeeze in between me and the vehicle I’m following, in the fast lane, causing my vehicle to slow and increase the gap. This vicious cycle happened over and over for a good hour before I finally shut the SOB (ACC) off.
I’m sure they’ve calculated the following distance for safety reasons and for allowing the vehicle time to react to its surroundings but this is ridiculous.
Now, I wonder if there is a way in Forscan to reduce the following distance. I don’t think it would be too dangerous for an alert driver to reduce the gap by 1 vehicle length which would dissuade most drivers from trying to squeeze in the lane ahead.
This chain started by expressing a concern about the shortest set interval not being close enough to work effectively in tight traffic. I'm running a 2017 so no adaptive cruise, but I experimented with a Toyota on a 1500 mile trip some time back. I found that I could manually apply accelerator and "override" or shrink the set gap while leaving the system active. Any time I let off the gas, it would fall back to it's preset. Not sure if I got TOO close that it would start braking (I assume so), but worked great for me on my trip. Again, don't know if Ford system responds in same way, but wanted to share the experience for reference.
