Even easier if you learn how to track-stand, which you can do on any non-coaster-brake bike (fixies are easier, but it's possible with just a freewheel and a slight incline or clever application of brakes). I usually beat cars through the intersection from a dead stop without straining.

I like the throttle for starting out with a heavy load of (maybe dancing / leaning) kids. Then I can keep my foot on / near the ground longer. Foot push + throttle seems to get me through intersections with fewer distractions than on my old bike.
