This really hits home for me. I live in Orlando, Florida and work is a scant 1.7 miles away. However, I do not dare drive or walk to work. Why? Pedestrian fatalities. This is a real shame not only because of pollution, and missed opportunity for exercise, but often because the traffic is so bad, it would only take marginally more time to walk/bike than drive. I really wish road engineers would ensure ALL roads (sans expressways/interstates) have protected bike/ped zones. Not just a stripe on the pavement that can be easily driven across by a distracted driver. But actual raised protection, like a median or curb.
