This might work. Well, actually I am pretty sure it will work
How to Tax the Rich: “But here’s the best part, from a psychology perspective. Imagine that anyone rich enough to qualify for this Infrastructure Tax gets to use all roads and bridges without paying a toll for the following tax year. Each rich taxpayer family gets two of those little transmitters that go on your windshield to automatically signal toll booths that they are paid up. (We have those toll transmitters in California. I assume they will be everywhere soon.)
Obviously the rich will pay far more in taxes than they will save on bridge and road tolls, but people like any sense of privilege.”
