Hello -
I definitely want the 55 MPH limit to return, but here's a proposed compromise :
cbs5.com - Rep. Speier Proposes 60 MPH Speed Limit
On the assumption that today's passenger vehicles have better aero than the advent of the original 55 MPH limit, then maybe 60 MPH would get you closer to the same savings.
Now, enforcement is a totally different can of worms.
