I wish there were more people going in my direction during commutes, it would be a welcome distraction.

I love when I look down a side street and see someone going my way one block over. I'll race them from afar and try and build up enough of a lead that we meet when I turn to go in their direction.

Yesterday I encountered the same guy twice because we were going in the same general direction but taking different routes.

Racing city buses can also be fun if you have a bit of a tailwind and the bus makes a fair number of stops.
