Last week, we did a 500 mile road trip and did not to the brake or accelerator for about 460 of those miles. Had one false positive incident ( slowed down abruptly under a flyover) . But overall loved it. For parts of the drive I had to set TACC to 80-85 just to keep up with the traffic flow. Would be hard to do that with a 75 cap . Do you know if it disengages TACC if you step on the accelerator ?
100% TACC is not disengaged when you accelerated.
It disengages only when you hit the brakes. Lane changes and stuff is fine.
I had worries with false positives on FCW but have not tried yet with new firmware 8.0(17.3.2).
