i'd like to give a big shout out to those drivers who have taken it upon themselves to restore safety to our streets and highways by driving 15 mph below the posted speed limit. often, you sacrifice your own safety for that of others by driving over the speed limit in order to get in front of the unsafe, maniacal, and reckless drivers who drive at the posted limit and then you promptly slow down to a much safer, much slower speed. so, thank you. your contribution to the safety of the streets and highways of america cannot be overestimated.
