What do you wish existed for your commute?

I want my Stuff to beep at me, or otherwise let me know if I'm leaving it behind. (You don't have to ask )

I'm just waiting for myself to forget my keys, and not realize it until I leave class and go to unlock my bike. It will happen. Except, of course, that would mean I forgot to lock my apartment. Maybe it won't happen. *fingers crossed*
