You should see the old steel bike I ride... if that sucker won't trigger a light, chances are a VW won't either.

Side story: The stop lights near my home didn't trigger for the 7 years I have lived there... I have submitted requests to the street division to get the loops adjusted... and they respond with "task completed." But the reality is, the loops still have not detected me on either my commuter (lots of steel) nor my cruiser (I think it was built from an old Buick... ).

Well I submitted my customary annual request, and this year (just a month ago) they finally adjusted them right.

I was quite surprised the other day to have the lights change for me early in the morning (when I was the only "metal" around). I couldn't resist and I rode out and right back to see if I could trigger them again... success!!!

I no longer have to run the lights in my own neighborhood...
