    I’ve had a Model Y for just over a month and noticed some interesting (to me) features. I don’t have FSD but I’ve seen the TACC (adaptive cruise) speed varies with the posted speed limit. This is a little disconcerting especially on highways when the traffic is flowing smoothly at 120km/hr (yes I’m in Canada) and the adaptive cruise speed suddenly changes to 100 or 90km/hr and I need to press the accelerator to once again keep up with the traffic flow.
    A second thing is that the autosteer won’t engage at a speed exceeding 10km/hr above the posted speed limit. This is obviously good for safety but if you are driving with TACC on and you engage autosteer, the car immediately slows to the speed limit plus 10km/hr.

    You can adjust how much faster than the posted speed limit you want to use. I'm happy with +5 mph. Also use the "set current speed" option as it makes staying in the traffic crowd much easier.

    Thanks Bob, I set the TACC to "set to current speed" as suggested and that helps my sanity. I also silenced the TACC chime. Do you know if there is a way to silence the auto steer chime as well. The best I could do is select "Joe Mode" to quiet the chimes but the warnings which sometimes try to correct my lane drifts are still loud. Thanks John
