Well, I do hate this. I want 1-tap for TACC and 2-tap for FSD. Traffic conditions both in town on the highway are just too variable and FSD does not do variable. I don't even know what the conditions are going to be until I get there.
I hope they implement a way to either enable TACC or FSD based on which button is pressed without having to act like a trained chimp changing driver profiles and putting up with all the hassles caused when your music or seat position changes based on the driver profile.
Yesterday I had to do a bunch of driving around town and FSD 12 was tolerable after I turned off the "minimize lane changes" option but it still made lane changes I didn't want, and I had no control over the steering.
It took FSD 12 to make me realize that I use and need TACC about as much as FSD and I use them both for different situations.
No longer having easy access to TACC and being able to select easily between TACC or FSD just sucks.
I'll keep all this in mind next time I need to buy a car.
