I love the mod, but I'm wondering if there is a way to change the speed of cruise control. I'd like at least one option to just barely creep along (like say 10-20% of the current "slow" speed (which I assume is just the speed you get if you just hold down W). My interest in this is because birds nests and some other loot (no matter what game/graphics settings I use) only render in when you're like maybe 5-10 blocks from them, meaning you have to go slow as hell if you want to search for them in a vehicle.
