Speed limit info is comically bad on AP2 / AP2.5, possible to update?

In Seattle mine is always wrong if I take the entrance to the express lanes on I-5 from Cherry street. Thinks I-5 is a 35 MPH road so you can't use AP until you get well north of Mercer and it picks up that it's actually 60. Probably an issue with the express lanes being underground and thus no GPS, but there are visual signs all along so camera detection would work fine.
 
Hi, any way to check if a tow package was included as standard on an inventory July 2017 build. My thought it was standard, but I am told inventory car came as is without one and have to pay to get one, plus it's back ordered. Was a painful experience dealing with my delivery specialist.
 
I also have a painful experience with AP2 hardware, the speed limit sign posted is 55 but the car autosteers at only at 45mph, slowing guys behind me, FUN! As describe about it also does not read updated speed limit signs.
 
I take 520 in Seattle into work every day. I usually will be running AP as it does well and there's an overpass when I go under it thinks I'm on and breaks HARD to get down to 35 MPH. So much fun.

I think I’ve experienced the same issue - it’s the last overpass on the Eastside before the bridge deck when you are traveling west into Seattle, right?

I always chalked that up to Tesla’s radar phantom braking, but next time I make that drive I’m going to see if the IC does reflect 35 mph briefly - maybe there is a GPS issue in that spot. Interesting!

Any overpass causes it. But this one is headed west, the Eastlake overpass on the old part of 520. Scared the crap out of me the first time it happened.
