Re: "National speed limit pushed as gas saver"
You're on very thin ice. Safe, "reasonable" speeds would be
much higher *IFF* everybody actually gave each other decent
following distance. As things stand now with as close as cars
generally seem to get, I'd say a safe speed in that ratpack is
about 35 MPH. You *cannot* determine your percentile from that
sort of situation, it's just pathologically, hopelessly unsafe
for 55 or anything in that area until these numbnuts *back off*
from each other.
