Point is Reagan himself ran into internal machines that he could not control. I would hope that now is a better time, because if we don't abolish it now, it will never happen, without a real revolution.
The 55 mph limit was abolished by the Republican Congress in 1995 and signed into law by Bill Clinton.
During Reagan's second term in 1986, states were given the right to set the 55 limit to 65 on interstate highways in areas defined as rural by federal regulation.
