More rest areas and all with a toilet yes. More and better road signs yes. At least cut away obscuring foliage so signs can be seen. I use one intersection in Aux where intuitively I'm going South to Hamilton but the Mway access is North with no indication that right lane is needed. Sort out merge like a zip rules so traffic flows better. Have congested left lanes preflagged so cars going through can get into middle or fast lanes. Much could be achieved with a big can of yellow paint stopping lane hoppers. I personally think fines are the wrong solution pull offenders over and make them sit there for 2 hours that might get a real behaviour change.
