A badge is what defines a car. When you see something for the first time, out there in the real world, you look to the badge to know what it is. Car companies spend millions of dollars and thousands of hours on testing and focus groups, just to get the right badge.
Zac brought up a great point today about badges and cars. Do you need a fun one to know you've got a fun car? What if my car is awesome, but my badge is boring? And who really cares about badges anyways? It's just a label, and we have too many labels in society as it is.
