Kinda like the "tax increase" they'll get when they can redirect the existing gas taxes to other stuff and let Texans pay for roads at the toll booth.
I'm amazed that there are Texans that think paying for roads twice, once at the gas pump, and again at the toll booth, is better than just raising the fuel taxes a bit. Or even better, spending 100% of the gas taxes on roads instead of using some for other stuff.
By definition, Texans will pay for the roads they drive on one way or another. It makes more sense to have just one method of extracting money from drivers at the gas pump, instead of gas pump AND toll booths.
If Texas politicians are incompetent at building and maintaining roads, they can be defeated at the ballot boxes. But a private monopoly on a road on a particular route can't be changed for 50 years, whether the company is competent or not (and since there can be no competition, what is their motivation to be competent?).
