If I could spare 15 to 20 cents per mile to give to this company (about $5,000 per year, for my family, based on present driving requirements), then I would agree with your viewpoint. Unfortunately, I pay more than that now in property taxes, so I'm not that lucky.
Even if you never drive on the toll roads, you benefit from them. Every car or truck they carry is one less car or truck you have to contend with on the alternate free routes.
