Cars featuring rooftop ads are quite common in New York. Some function as mobile promotions for Broadway shows. Most are for restaurants and the majority of these are for chains like Domino’s and Pizza Hut. I was amused to see the automotive billboard concept used in Wroclaw, Poland. Schnitzel for 9 zloty (that’s $2.83 US) and they’re open 24 hours a day. Consider me sold!
