Ran into a dilemma this morning that appears to be a fairly large design problem. Surface street, normal speed limit 45 MPH. Approaching school zone, speed limit 25 MPH when the yellow lights are flashing (they were). I like to set TACC in school zones like this to prevent me from going above the posted speed (cops frequently watch this street and this school zone). I tried several times to set TACC to 25 MPH, and I can't figure out how to do it. Every time I tried, no matter if it's a half-click down on the stalk, full-click down on the stalk, click and hold, etc., TACC always set itself to speed limit + offset = 50 MPH. There isn't enough time to press and hold the "minus" button on the display 5 times to get the set speed down to 25 MPH before I'm going way too fast. I the S, you can set TACC to the current speed regardless of the speed limit by a half-click up or down on the cruise control stalk, but no such way to do it in the 3. Am I missing something here or did Tesla just b0rk this interface?
