Finally got 25.2 last night: The Evils of the Once-A-Day check, really. Took it for a spin today. Not very heavy traffic.
- Still slow turning right, but it gets there.
- On a wide single lane, when turning left, it still swings wide right before making the turn. (When turning left, vaguely hug the center yellow, don't head for the curb on the right. The car always swings to the right on left turns. Who programmed that?)
- Handled a left turn at a 4-way stop, with another car at the intersection, cleanly, properly, and at about the same speed a human would have done it. Haven't seen that before.
@AlanSubie4Life, a bit ago, described what sure sounded like an underdamped control system on what should've been a smooth stop: Braking, followed by hard, non-regen braking, followed by gassing it, lather, rinse, repeat for the distance it took to stop. Odd, I thought: I hadn't noticed that. And having a linear/digital control theory background, that's typically the kind of thing that I'd've noticed. So, on this 8-mile round-trip, I was looking for that, every time the car came to a halt in traffic, which happened a few times.
Result: Mostly smooth stops. One where a smooth stop went to a bit harder stop. And one, where there was a red light (and one car waiting at it) preceded by a blinking yellow, where the car came to a near halt at the blinking yellow (it's in front of a fire station), then motored very slowly up to the halted car, a couple hundred feet up.
But no oscillatory action. Hmm.. Dunno, we had a contributor to this thread mention that a replacement of the driving computer fixed some FSDb problems he was having, implying that there was something hardware-like wrong with the replaced computer. Or that a computer replacement truly-duly effectively wiped some code that should've been wiped long ago, in the driving computer or elsewhere.
I'll drive some more over the next few days looking for the oscillatory action. But how common is this, anyway?
