Update -
I got some more driving in today, and can confirm that the shift lights do exist on my HUD when in sport mode, however i'm only able to see them in 1st gear. Since i'm still under my break-in and under 500 miles, i'm trying to keep it under 4k rpms in any gear, but in 1st I saw the tree pop up at 4k rpms, while in the other gears (2,3,4), I didn't see it activate at that rpm. Perhaps it shows up only at higher RPMs in upper gears? Or, is it really only in 1st gear? I'll have to get past break-in to find out
