Social science experiment
March 23, 2012
Try this experiment. Take a bicycle out to a bike trail with any significant traffic at all. Pull off to the side, and start fiddling with your bike. Every third person will stop or call out to see if you need any help.
Next, try putting the hood up on your car, parked on a busy street (Massachusetts Avenue, Arlington, in particular). Stand next to the car facing traffic with some jumper cables in your hand, out where drivers can see them, almost as if you needed a jump to start your car. Dozens of cars will drive by and many minutes will elapse before anyone will stop to help (at least, that was my experience today).
Draw your own conclusions.
