>>4637164its not gimmicky. its actually very helpful.
OP, my father has a '03 corvette and it has this HUD too. It helps me a lot because rather than look at the RPM and the road back and forth, my focus stays on the road but I can see the RPM, speed, other gauges, mileage (it basically shows everything via switches)
it just helps so you dont have to take your eyes off the road
