Just got Beta 10.3.1 last night and did my morning commute into D.C. It handled pretty good, though my drive was a relatively simple one. For anyone who know the area, the trip was from fairfax County Parkway in the Herndon area, down to Braddock, over to 495, and then onto 295N.
I activated while still in my driveway and it attempted to make the left turn out of my driveway and it might have made it but I didn't want to accidentally hit the fie hydrant on the other side of the cul-de-sac street. Was pretty timid making the next two right hand turn in the neighborhood. Right onto the parkway was good with no traffic. All the way down to Braddock was smooth and didn't have any issues with cars merging in from the right on-ramps. I had one phantom braking event with no traffic around and I did the video capture and will email report it. It may have been an overhead sign or maybe an off-ramp, or maybe something else.
The car got a bit confused at the left turn onto Braddock and though it got through ok, I would have intervened had there been a car in the right hand left turn lane next to me.
Getting onto 495 was a little issue. There are 2 merges while on the on ramp. The car handled the first merge with traffic great though there was already good spacing between cars anyway. The second merge with traffic it god confused and started to brake like it was going to slow way down and I intervened because it would have just made a mess of traffic behind me.
Onto the 495 was good and it was able to move over multiple lanes with no problems. The only issue with the lane changes for me is that I wish it would check for a safe lane change BEFORE turning on any turn signals. I wouldn't have a problem with it notifying the driver of a lane change ahead of time but around here turning on the turn signal just tells other cars to block you. There were a couple lane changes where it was perfectly clear but the actual lane change initiation after the turn signal was turned on took way too long(multiple seconds).
Onto 295N was great. 295N was pretty much stop and go, 2 miles to travel took about 25 minutes. I almost always(at least probably 80% of the time) have problems with AP on 295N so I only use AP here after updates to see if anything has improved, and it never has. The problem is that while on AP, the car will decide to start active tracking a vehicle in an adjacent lane(even when there is a vehicle in front of me). Depending on where that other car is and what speed it is going or if it is braking, my car will decide to hard brake and I have to intervene to not piss off the driver behind me. Today, while on FSD it went through the area flawlessly. I will not claim success however because it could have just been a fluke. With the amount of volume and the lower speeds, it may have been a better environment to analyze.
Anyway, that is my trip report!
