I feel like what you've been saying about extremely high gears is true if and only if power management is not a concern.

It's called a shifting gearbox.
My point is that with a shifter you don't need to worry about power managment, as long as you are either a) careful and shift or b) use encoders or other methods to automatically shift down in collisions. I prefer the latter method, as the first has much less use.
