Did my first road trip yesterday. I went from Portland to Seattle, 180mi, last night. Used TACC for the entire trip with it set at 75 for half and 68 for the second half of the trip. It worked flawlessly 100% of the way. It was amazing. I've never used TACC before on a road trip. I also used autosteer for the first half hour getting out of Portland. It worked perfectly also. At first it kept disingaging because I was trying to put the car in the part of lane where I wanted it to be. After I decided to just let it do its thing it worked perfectly. Not one single nag or disingagement for over ten miles. Amazing car. Truly amazing. Thanks Elon.
