The gas tax is 18.4 cents a gallon. My car gets about 30 MPG, so the tax works out to .61 cents per mile, or 163 miles for each dollar of tax.
I live in New Jersey. The New Jersey Turnpike is supported by tolls. To drive from the Delaware Memorial Bridge to Exit 11 (my exit) costs me $7.25 for 90.6 miles, with works out to 8 cents per mile.
So the Turnpike Toll costs me 13.1 times as much as the gas tax!
I have no problem with usage fees instead of gas taxes... tomato/tomahto... But I got a big problem with a 1310% tax increase. And I suspect the usage fees are going to be a lot closer to the NJ Turnpike Tolls than are to the Gas Tax.
There is a toll bridge across the Mississippi in Louisiana, the Sunshine Bridge. Named after Governor Jimmy Davis, who had a gold record, “You are My Sunshine”. When I was a child, the toll was 35 cents. Today, the toll is a whopping: FREE. After the bridge was paid for, they got rid of the toll.
