If you don't know someone there are still many good reasons why you would follow them on Twitter. I get the obvious reasons, if you are trying to build your business, create a larger network, or start a community based on shared interests.
But just following them because they drive the same route you do everyday and sit in the same traffic seems a bit of a stretch for the online social media "community" don't you think?
That feels like social media loneliness to me, and reminiscent of the "masses of asses" direct marketing approaches of old.
Or maybe it will transform Twitter into another online dating service, allowing drivers to pick people up based on the make, model, year and color of their car?
If you are curious, get your own Tweet My Bumper sticker here. I know I am going to be wathcing for them, if for no other reason than the sociologist wants to see what else forms of it.
