How I deal with FSD's speed-limit misreads — and the I-35/I-29 speed trap

FSD still misreads speed limits, mostly in construction zones, and I've found a way to live with it. The trick is the speed profile. If I'm in Standard and the car's pushing too hard, I drop it down a couple of notches. If I'm in a hurry, I'll at least pull it back to Standard. It's not ideal — you shouldn't have to babysit it like that — but it keeps the car from overdoing the speed. There's one stretch I watch closely: I-35/I-29 on the north side of the river. The limit drops to 55, but traffic is usually running 60-plus, and FSD wants to keep up with the flow. That's a speed trap. I'd love it if FSD could learn to recognize those — the spots where the posted limit and the moving traffic don't agree.
