2021 map update, C470 speed issues

[IronCoffee_Max]

One thing I had hoped to see in an updated map update was a fix to C470 where it thinks the speed limit drops to 45 while on the highway. I assumed it primarily happened due to old map data since C470 was redone completely in the past few years.

People call it phantom braking but it’s not - it’s the actual speed limit dropping in maps so it drops TACC speed causing the car to slow down.

I’m curious if anyone else has seen the same thing and how to specifically report the error.

Several people have posted about this over the years. I noticed several months ago that the issue had improved slightly in some areas. However, I still have the problem with the incorrect speed limits when close to the exits between Santa Fe and Quebec. I was hoping the updated maps would finally fix the issue.

Does this occur in 'current speed' mode instead of 'speed limit'?
