Doesn't on my game on Xbox. Have you set the speed to change automatically in the settings? Because the only way I could replicate this was to force MPH in the menu.
Mine is set to change automatically in the settings. Everything else is displayed correctly. The speedo and the hud etc. If I have the next speed displayed in the hud, then it is correct. It just appears to be the "next marker" that is wrong.
This can been seen in the photo, HUD is correctly displaying KPH. The next speed marker is displaying MPH. Like I said, my measurement units are set to auto.
Oh I don't drive with those on. Well you've logged it, and the developers read all these technical reports, so they might provide an update at some point.
