Just went for my first drive with 10.69.3.1. I thought I remember hearing claims that this new FSD beta used a single stack for AP & FSD, but that clearly is not the case. I was impressed with how it behaves when being passed on a two-lane road; the car moves to the right to assist the passing vehicle.
I am not pleased at all with how it still behaves in several scenarios:
- Constant phantom slowing for no apparent reason. Even though by just a couple of mph, it makes for an uncomfortable drive when it happens repeatedly a couple of times per minute. It is enough to cause me to lean slightly away from the seat.
- Vehicles crossing my lane ahead of me that will clear the lane before I get there; FSD still slams on the friction brakes (i.e. my seatbelt locks and I am thrown against it). Release notes have made multiple claims to have improved this.
- FSD keeps moving me out of the right lane into the left lane and won’t let me stay in the right lane, giving the message “Changing out of rightmost lane”. It does this on US-31, a four-lane highway (but still using the FSD stack, as is apparent from the visualization, as well as the fact that I have automatic lane changes disabled in FSD). If I try to cancel the lane change, it just tries again 30 seconds later, repeatedly, until I give up and let it. And, yes, I have set AP to stay out of the passing lane, but that affects only AP, not FSD.
- Excessive and harsh early braking (using the friction brakes) when approaching stops, then slowly creeping up to the stop. Not the nice smooth braking anyone use regen would do. A computer should be able to execute this at least as good as any human. It is a simple problem. I have taken to canceling FSD and slowing using regen, then reenabling after I stop.
- FSD takes forever to lower the speed of the vehicle when the speed limit reduces. I would say at least a quarter mile—definitely far enough to get a ticket in the typical speed trap. I have taken to canceling FSD when it goes down a reenabling when I reach the new speed.
I guess I ought to be treating FSD like the proverbial talking dog, where, instead of criticizing his grammar and pronunciation, I should just be amazed a dog is talking. But there is no way this is worth $15k for new buyers, nor will it be in the near future. However, it is worth the $2k premium I paid for it on top of my EAP I had to pay $5k for back in the day. But it is also frustrating enough that I am likely to disable FSD when doing non-Interstate highway driving. It is nowhere near as stress reducing on a Highway as EAP.
