Today I was using TACC around town to maintain speed limit in traffic on surface streets, and I observed two interesting things: First, I was driving down a street at 30mph, no cars in front of me, and ahead there were cars stopped at a stop sign. I was about to apply the brakes, since TACC is not supposed to be able to distinguish stopped vehicles from road, however the car started slowing and came to a stop by itself! Second, after coming to a stop behind cars stopped at a stop light with TACC enabled, a "HOLD" indicator appeared above the speedometer, and when the cars in front of me moved when the light changed green, the car did not move and an alert appeared at the bottom of the IC (where the "keep your hands on the wheel" usually appears) saying "Press accelerator to reactivate TACC" (approximately). I tapped the accelerator and the car then proceeded to accelerate on its own and resume TACC. Anyone else seen that before? I thought perhaps it was after sitting without moving for a certain period, but that doesn't make sense since it happily sits for long periods in freeway stopped traffic and then continues moving when traffic moves.
