Creepy Carpool 101

The idea of getting into a car with a complete stranger is foreign to me, especially when it doesn't involve asking the question: "Can I get a ride with you?" The whole notion that I can walk up to a car and open the door and sit down next to someone I've never met, and have them say good morning, as we drive off across the bay, somewhat freaks me out. But for $1.00 from Oakland to San Francisco, you really cannot beat that.
