Not really to do with this post but...
Why do american cars have little reflective light things on BMWs? I notice from your profile pic that the Z4M has little red ones at the front too. Is this a safety law or something?
Yep - supposedly increases visibility when entering an intersection. My 2003 doesn't have them because that year the reflectors were integrated into the headlights.
