I've been noticing that yes, cars still have cache when it comes to selling products through the lens of love, but what about transit? You'll never see a bus on an advertisement for love or pants for that matter but you will see streetcars. Why? I'm sure there are lots of reasons. But as you can see, there are a number of examples including Slacks and Personal ads. The dockers ad and Yahoo! personals ad are both set using San Francisco Streetcars. I even noticed at one point a Hummer commercial set in St. Louis (UPDATE: Commenters have noted that it isn't St. Louis but Edmonton) that had light rail in the background. Talk about subtle, see if you can spot the LRV in the 'Urban Techno' commercial for Hummer below.
