According to the National Highway Transportation Safety Administration, speed isn't a big killer on U.S. highways. The biggest cause of accidents: not paying attention. So, keeping speed limits low while letting people talk on the phone while driving seems to be working, right, people? I'm not advocating higher speed limits (it's more important to conserve gas than anything), and we have to keep kids in car seats and wear our seat belts, but when it's so obviously clear that distractions hurt people, something should be done about it.
