Hi. I made a car that has all R, N and five more gears. Left SHIFT and Lest CTRL buttons are used to switch between higher and lower gears, respectively. You can search it with the name "Futuristic Car with Realistic Gears" in the Workshop. Waitng for your opinions and suggestions. In the meantime, it also has two cameras activated with a single button (C) and lasers (activated with R).
