You're overestimating how important shifting is once you're already in motion. Sure, you won't be in the optimal gear, but I've seen people drive for surprisingly long amounts of time in the wrong gear because their hand was occupied doing something else (phone, eating, drinking, what have you). Additionally, you can keep your phone in your hand while moving the shifter.
