Cars and robots are two different things. On a car you know when the optimal shift point is. You're also only concentrating on one thing--staying between the white/yellow lines.
With a FIRST robot you're doing a multitude of things, and anything that allows the driver to have one less thing to think about is going to give you an advantage. It's like having a 4 speed transmission--does the driver have time to think about what speed he needs to be in, how much current he's drawing, etc, or do you just make an algorithm that shifts automatically to always keep the drive in the gear that gives optimum performance for a given situation?
If you think it'd be hard on a driver to find the right gear instantaneously with a 4 speed, think about how much thinking it'd require with an infinite number of gears.
