I tried my standard interstate highway test run using v7.1: a 40 mile round trip for take-out sushi (I live out on a horse farm). The car nagged twice going out, and three times on the return. As I recall, the most nagging in the past had been twice one way and once the other. When AP first came out there were no nags at all on most of these runs. In total I have done perhaps 20 of these same runs on Interstate 66 with AP on. I assume these nags are programed, since if they only occur when the system is unsure of itself, then that means AP has been regressing, not improving. Conditions were fine today: going out there was good lighting from behind just after sunset, with no shadows and traffic light to moderate. Coming back it was night with clear weather and light traffic.
But the worst was passing a truck at night on the way back: as I was about to overtake the truck on a gentle right-hand curve my car began to swerve nearly off the road to the left. I grabbed the wheel and the system disconnected. I was going 80, him 75, with the speed limit 70 and no other traffic. Very bad. It shakes one's confidence.
I assume that AP would be much less of a hassle if you left those "nags" on the horse farm when you travel :biggrin:
