Republicans in Harris County sold voters on the Beltway 8 toll road in the 80s based on the idea that when the bonds were paid off the tolls would go away.

Clever hack: they never stopped issuing bonds.

At least they've made it really easy for them to take your money. You don't need a toll tag, they'll scan your license plate, mail you, and charge you extra for mailing you. No coins needed.
