Reading many of the threads here about people having issues with TACC and Autosteer, I am wondering if my experience is unique. These days, I would say 90% of my driving on freeways are on TACC. I have also recently completed a 800 mile round trip from Bay Area to San Diego, largely using TACC as well. I also drive 10-15 miles most days using Autosteer as my commute sees heavy traffic moving anywhere between 30-50 miles / hr. My experience has largely been trouble free. I do a few things while using Autopilot - make sure I am in the middle lane, set a distance of about 5 car lengths, take over during ramps. I am wondering why my experience is different than many in the forum. Is it because I drive in Bay Area and California and the roads are better mapped by Tesla ? or is the software optimized for CA lane striping or is lane striping better around here ?
