Double Nickels - The old double nickel speed limit was the most abused rule in America. I think the police gave up trying to enforce it or gave such small fines in some states people didn’t see it as a problem. The 55 mph speed limit did create a rather strange situation where speedometers in American cars were banned from showing speeds above 85 mph. I believe this was scrapped in the eighties as well.
Mine is like that, but it’s a digital LCD. A few years back, someone discovered how you could jumper two pins to let it read all the way up to 199MPH. Apparently Ford wanted to keep their options open :^)
IIRC,during the 55mph years,some truckers blocked an interstate by riding side by side at exactly the speed limit.
Caused a massive traffic jam.
