It wasn't oversight, it was a deliberate design decision so you can tell if you're in auto or manual mode without looking down at the stick.

When in M mode it shows you M and the gear number, I was just wanting it to do the same in D, but when it's displays D the number part that is blank and when in M it shows you what gear you're in that's all why no gear number in both modes is all I was woundering

has anybody noticed the revs dropping down to 1000ish when you let go of the throttle.

say im in 4th at 3000revs and I let go of the throttle. it just drops down to 1000ish revs and the moment I hit the throttle again it jumps back up to 3000

this is annoying if I need to downshift because I look at the revs says its 1000 I shift but the actual was 3000 BAM 4000 RPM

Yeah I get the same, let go of the throttle and the rpm drops to a bit below 1000.

I guess it has to do with saving gas?

but it not fun when you cant see when to downshift unless you touch the throttle to see the real revs

I use both but more the stick than paddles. When I do use the paddles, usually it's when I'm driving in a straight line.
