I just picked up our Model 3 with retrofitted FSD computer, and I’ve noticed some slight changes both good and bad with seemingly the same software version 2020.4.1.
Here’s a residential curve that I would normally take at 20mph, and with HW2.5 set to 15mph would consistently fail while FSD computer consistently handles it at both 15mph and 20mph. It’s not a sharp turn like a normal 4-way intersection, and there’s only a lane line in the center of the road during the curve and curb on the right side.
Here’s the start of the curve to get a sense of how sharp it is:
And the end of the curve with line that ends and curb out of view:
Both HW2.5 and FSD computer display a confused right lane line:
I’m guessing the FSD computer happens to react just slightly faster to predict where a lane would go after the curve to not show the big red wheel “take over immediately” warning.
Here’s another curve that FSD computer now consistently completes; although it’s still a bit scary / late to react. This is probably difficult because the lane line disappears for an intersection at the very beginning of the curve, but perhaps FSD computer again is just slightly faster to pick up the line just after the intersection to immediately steer left.
Here’s a split from 1 lane to 2 where HW2.5 would consistently end up in the left turn lane, but surprisingly FSD computer knows to keep right even without a lead vehicle.
And for some regressions with FSD computer, here’s an intersection where HW2.5 would sometimes fail earlier in 2019 but later software including 2020.4.1 would correctly keep right through the intersection. FSD computer wanted to swerve left into the oncoming left turn lane and showed “take over immediately” because it knew it made a mistake of wanting to drive into the bus.
And this last regression is surprising as HW2.5 never had an issue while FSD computer shows “take over immediately” perhaps realizing the bike lane is not big enough for the car.
