I'm struggling to see how this is possible. You'd have to know your initial velocity for this to work, which sort of defeats the whole purpose.



We did an acceleration/velocity test with our robot (ballshifters) earlier this year. In high gear, from a standstill, the robot catches up (position-wise) to itself in low gear within four feet. If you shift, you'll also lose energy during it. Automatic shifters are not worth it.
