I have driven over 20,000 miles on my MY since I got it in December 2020. Most of that from April to October of 2021. Based on my experience so far, I had decided that I would not get FSD unless it offered better driving experience than the standard AP. So, I came looking to this forum to see if FSD offered better driving experience than AP. If so, I was going to try one month of FSD to see what it was like.
Looking through the posts, it seems like FSD does not offer better experience than AP. (I'm curious, when did they stop including radars in Model Ys? Does Tesla use infrared sensing?)
My experience and thoughts.
1. I do not use auto-steer in construction zones. Several times the car would not move to avoid obstacles. An example was on an interstate at night through a construction zone. The marked single lane I was on veered right with a large parked truck directly in front. For some reason, the car did not follow the lane. I waited as long as I could before manually overriding. Who knows, the car might have acted correctly but it was getting too iffy for me. Also, the car sees cones and lane markers, but if the cones are on the traffic side of the marker, the car does not seem to take that into account. It still tries to center using the lane markers.
2. The cruise control has been pretty good generally. However, there were 3 times when it did hard phantom braking. Once it was due to an overpass that was coming up (I think - it may have been for some other reason). This was on a clear day. Another time it hard braked for no reason. Again on a clear day. I forget what happened the third time. There have been numerous light braking. Now when I'm driving, I have to be alert to press the accelerator in case the car decides to slow down or brake hard for no reason. I imagine many cars behind me got annoyed.
3. It's really irritating how the car tries to auto-center when autosteer is first turned on. Why does it need to center hard immediately? It should know what's in the surrounding areas. Why not center more gradually unless immediate action is needed to avoid a collision? Similarly, why can't Tesla follow the left lane marker when in the right-most lane and right lane marker when in the left-most lane? This would avoid problems with trying to center as the lane gets wider for exits and entrances. I'm surprised I haven't gotten pulled over for DUI because the car veers right and then moves back for exits and entrances.
4. If the car tries to stay in the center of the lane, why does it sometimes move to the outside of the curve when following curves in the road? On two lane roads, I can imagine this would be very disconcerting to oncoming cars to see a car wandering toward them. The car does not cross the median, but still I don't know why the software can't be tweaked to center the car on turns.
5. But AP works very well in heavy rain. I was caught in heavy rain several times, and the car had no problem keeping itself centered in the lane even when I had a hard time seeing the lane.
6. Which reminds me - the Auto wiper mode leaves a lot to be desired. It had problems with snow last year and rain in the warmer weather. It wouldn't turn on in a timely manner. Sometimes I'd have to press the button to intermittently turn it on until it did start automatically. Sometimes I had to turn it on manually because it never did turn on. Sometimes it doesn't turn off. The rain may subside but the wiper still goes too fast such that the wiper will squeak against the dry windshield. And sometimes the wiper will turn on when there are too many bug spots on the windshield. That wouldn't be bad if the cleaner was sprayed, but no, it just keeps trying to remove the "rain."
Well, that's what I can think of now.
