I started using Waze recently and noticed that with Cruise control set at 80 Waze reads at 77-78. Moving Cruise up to 82 reads at 79.

Stock wheels/tires with 12/15mm spacers.

Anyone else notice this or is the phone GPS just off?

from what I’ve read in this forum and online, BMW apparently (purposely) sets their speedos lower than actual speed. the speedo on my 2021 always reads 2mph lower than any visible radar I’ve come across

Yep, definitely 3-5 mph off.
My dashcam is equipped with GPS speed and it always shows the lower number. Looks like the speedo is a bit optimistic 😊
