No I think you need to put yourself in the highway department supervisor's position.I've always thought about this: Do you think Lobbyists, from the Auto Makers, make a Run at pushing the use of salt, and now the New Liquid Brine solution, on the roads here in the NE, just to Destroy Their Products over a shorter period ? We all know cars will run forever, with Basic Maintenance. Can't sell 'em, if they just keep running ???
You need to balance public safety, a budget and manpower. Rusted cars are not really high on the priority list.
That said I do wish they would just drop the plow Sometime and leave the spreader off.
I consider myself good at driving on slippery roads, unfortunately many people aren't.
