Ahh, parking as everyone waits in line to angle back against the curb or in a line after a run or something, and you know they're watching the trike guy. Hey, no problem! Try getting used to doing this a few times when you go places by yourself, it pays off:

Pop it in neutral to get the N and roll past your spot as you turn out to the left; just before stopping hold the R button for a couple of seconds while you stop, swing the bars right, and look back. The R should be lit by then. Thumb off and back on so you're backing up within a second or so of looking. You'll get the hang of it. Back alongside the previous guy, let go and coast to a stop. Matter of fact, if it's downhill backing to a curb, once you pulse the R for a second to get it moving that way, kill the motor as you roll back before you even stop! Either way, turn off the ignition while putting the parking brake down if you use it, hop off and casually walk away as if it tweren't nothin'.

Drives 'em all just freaking nuts! You'll be in your spot as quick as or quicker than anyone else, effortlessly, not a chance of dropping it, and no pesky Jiffy stand to mess with either. Sorry boys, no show today, find someone else to entertain you!
