My local Sheriff's Department has those MPH trailers all over town.
My speedo has always read 5mph slow at city speeds based on these devices.
But in the past 3 weeks, it's been reading SPOT ON!
Anybody know of a reason a speedo should suddenly start to read slower?
If anything, as the front tire wears, it should read faster.
I think 'ol Mr LEO has come up with a new strategy to slow people down.
