alt Hacker NewsThe fastest highway in the United States is the 85 mph controlled access public-private venture toll road east of Austin. State income tax is not a thing in Texas, and that road would have otherwise not been completed at the price or schedule it was built on without the backing of the private company that built it.
Why would you tax people's income to pay for a highway? Fuel taxes and license fees would normally be the way to pay for transportation infrastructure.
