They don't need a recorder, the Penn Turnpike did that for years and may still do so, when you entered the turnpike your entry ticket was stamped with where and when, as you exited the time and distance was calculated and if you got there too soon you were cited.
It would be a VERY simple thing to install gates at entrances and exits to any limited access road and do the same thing, they could then add a toll as well which would eliminate the "freeway*" concept, wouldn't it? :-(
*Called "freeways" because they cost the taxpayers millions of dollars per mile....
