Google Maps tests new pop-up ads that give you an unnecessary detour

This is a most excellent place for technology news and articles.
Anecdotal, but a friend of mine was ticketed for it within the first week it went into effect. She (understandably) assumed that being stopped at a stop light was acceptable. That said, I'm not aware of any enforcement since then and wouldn't be surprised if they deliberately only enforced it right after it took effect.
Still wouldn't risk it, though.
