So now since FSD came out, decided to make a quick trip down and back to visit some relatives.

I utilized FSD for about 97% of the trip.

1,184 miles with 460 kWh for 388Wh/Mi on mostly highway driving over 47 hours so not bad.

Charging was simple once i charged just a little extra at the first stop. They had me arriving with 4% each stop, but that in my book is unacceptable so i just stayed a few minutes longer to make sure i had a small buffer. It wasn't to 80% for the charging either for each stop, just enough to get me to the next charge point they decided.

Drove with FSD whenever practical. Those non practical times i disengaged it because it really pissed me off until we were out of those situations.

Some of the things that forced me to disengage (in no order):
1. Following too closely - at 70mph it was literally 25 feet from the car in front of me flying down the highway and imho there is no way i can stop in time.
2. Racing up to the car in front of me and then applying the brakes too strongly (us going 70, them going 55). This happened numerous times and even ran up to a car at a stop light pretty aggressively to the point everything in the backseat was slammed to the ground as we ground to a halt. Doesn't happen all the time but I have noticed in TACC that this never happens and it utilizes regen breaking and the brakes at a consistent manner to make sure it’s not slamming on the brakes.
3. In WV there are some winding highway roads that have a 70mph speed, but they tell you to take the roads at 45 because the curves are too tight. FSD didnt care and tries numerous times to take the curve at full speed. It would do this and then either ride the line or just go over the line about a foot into the shoulder/other lane. The G-forces would literally hold me into the door! Totally unacceptable especially if there was another car there or lord forbid rocks/cliff/barriers etc....
4. FSD i would say 60% of the time manages to stay in the middle of the lane. The other times it loves to hug one of the sides (never went over the line unless the curve was too sharp though). This is stressing because other drivers tend to do the same thing or just start to vere into your lane during a curve and you dont have much time to react.
5. We all know truckers out there are tired and overworked and sometimes have trouble staying in their own lanes during curves and even straight aways. Overtaking a Semi on a tight curve is usually a no no as they can never seem to stay in their own lane. CT FSD didnt care at all and would sometimes hug the line next to the semi. Came way too close too many times in even little curves and some straight aways so if i had to pass some Semi's I manually did it. I usually get to the opposite side and then speed up to quickly pass once safe.
6. Speed limits - I dont think FSD knows what that would is. It says natural flow on their let the CT decide mode but many times i was the slowest car on the road or i was going 69mph in a 55. You can speed it up by pressing the gas but slowing down is impossible unless you disengage or step on the break thereby breaking fsd. (refer back to racing up to cars in front and riding their tale)
7. Road Rage - sometimes you don't want to honk to save cam data when an idiot does something to avoid pissing him off even more so remember how to save it in case you need it later.
8. Speeders - they are out there. With FSD going 68 in a 70 in the middle lane it choose to turn into the right lane to make a turn. Unfortunately some idiot doing 90 was flying down the right lane as the CT FSD started to move over. The turn was safe imho but the cameras that were detecting these vehicles around me didn’t know that one vehicle was moving at a larger speed and would cause an unsafe situation? Apparently not, I didn't get hit but he quickly got over to the middle lane and then quickly cut me off in retaliation.
9. Wipers cleaning with fluid or without during FSD. Still have not found any data on this but apparently it happens even if your windshield is perfectly clean...
10. Mirrored sunglasses will work but FSD doesn't really like them depending on the angle of the sun
11. Still having issues with 4 way flashing red lights

Overall it was a great trip minus the issues above. Great wh/mi with 388 wh/mi during the trip. Plenty of interaction at stops with people asking questions and if i built it myself lol. No bad interactions im happy to say.

Nice write-up. I don't like how FSD rides the lines either. There are some kinks to work out for sure. I've driven FSD for ~200 miles at this point. It is much, much better than I thought it would be. This weekend I was easily able to imagine being driven around in the backseat by the car. It is a cool thought. For now though, I still watch it like a hawk.

I’ve driven with FSD for about 150 miles on controlled access highways and haven’t seen the speed issues, or following too close issues you described. Lane centering wasn’t perfect but was better than I usually do. I observed the FSD system edging away from adjacent trucks that crowded my lane.

I wonder if some of my FSD configuration parameters are different than yours.

I have day dreamed about that too about sitting in the backseat while it drove me.

Running FSD so much this weekend I had to double check to see if I was I was manually driving or if it was in FSD because sometimes I forgot which mode I was in lol. It is a great option if you don’t mind a few snags.

That’s what we have become now. Instead of the driver, we now became driver supervisor. Just checking if it ll do the work fine, interact if needed lol

What had you arriving at 4%? That definitely doesn't sound like the Tesla Nav, which is more like 20%.

Unfortunately it was Tesla Navigation. Hence why I just charged a little extra to make sure I didn’t have issues. I wish you could set it to arrive by a certain % that would be great to alleviate any traffic issues

Excellent review. In my experience in my CT CB, I agree with all your points, especially the tailgating issue at 70 mph. Happened to me this morning and I took it out, pulled back and then passed the slow-moving car and resumed.

Thank you for taking the time to write this. In my Model Y I had a similar experience, and Tesla nav keep wanting to get me to to the next charger with single digit battery percentages, I did the same thing as you and over charged each time. I wish this was a configurable behavior.

In my case I was traveling through the desert at 100°-115°. From Houston, to San Diego is 25 hours of mostly uninhabited desert. There was no chance I was risking running out of battery and AC with my family in the car.

Were you using ”auto” speed? Or using the manual max speed? Mine asks me everytime I get in to use auto speed, I have to dismiss it.

I use AP and now FSD a lot and have driven a decent amount with it (maybe 60-100k miles? probably more) on non-CT teslas. I think the braking curve of the CT is very different than any of the S3XY series, and initially it's a little unsettling--it feels like it's braking later than on those other vehicles. But inevitably it stops, and I haven't had any close calls. the initial part of the braking curve seems very light, like it isn't stepping on the brakes enough; then, toward the end of the braking period, the truck decelerates fairly quickly, but not in a lurching fashion, to complete the braking.

the lane following on curvy roads on a segment I drive often mirrors my X and Y. all vehicles straddle the lines a little. some FSD releases have been better than others for this. I am sure they will be able to optimize it.
