With this jacket, I have ridden past cars stopped at traffic lights, and have seen people throwing their mobile phones on the passenger side floor of their cars as they were facebooking .... (you get a huge fine if you are caught using your phone whilst driving)

wear one of these, and you are like Moses parting the waters .... cars from the rear slow down and pass wide.

They tried to ban these in the UK, but eventually they were passed. Really good at night aswell, as the reflective strips are very bright .... The UK police wear the same colours .... they also come with black trim/full length sleeves:

Clothing made almost no statistically significant difference - 1-2% of drivers always drove dangerously close. Only two outfits altered driver behaviour - one which said "police", and another with "polite". The latter is an intentional imitation popular with cyclists and horse riders.
