All this chatter about seat sensors and the like is fine but, what I have dreamed about over the years is an electric toilet seat heater that will quickly clear the lav when it's time to head back for some "relief of physiological needs." Nothing like trying to outwait someone who has homesteaded on the forward "throne."
You want to take a break from "saving everyone's life" and get on with a good pee and your stuck in traffic. A 115VAC 400HZ toilet seat heater could do the job in short order.
