Last month I knew we had a lot of long trips planned, so I signed up for a month of FSD ($100). I'm on an older version, which is the most stable. We're going to KC on Saturday, so we'll see how it drives. We took it to Omaha a few weeks ago:
1. I put in our destination in Omaha, pulled out of my driveway, and let it take over. I had it set to "hurry" mode, and it performed perfectly on I80. I did limit its speed to 80mph, because there were times when it was going 85mph.
2. In Omaha, I found "hurry" mode to be too aggressive with lane changes. It was in the far left passing lane, it had 3/4 mile until the right exit, so I disabled it and started driving.
3. While driving around Omaha, I used "normal" and it worked good.
The only thing I didn't like was that it would turn on its turn signal for a lane change when it was beside a car, which has a tendency to freak out other drivers. It didn't change lanes until it was safe, I just didn't like when it signaled for a lane change.
