The road-tax is neutral, it doesn't matter what goods you transport. Imagine charging the producers of the most transported goods to pay a fee in addition to the road-tax and otherwise blocking their goods being transported for the rest of the month.
Net neutrality asks the internet to work how road taxes work. You pay for a certain bandwidth (a truck) and you can transport whatever goods you want with that. It doesn't matter if you go to walmart 5 times a week or split your trips to costco, walmart and target. Or maybe whole foods has a deal with the state that makes the people driving trucks to them exempt from the additional fee.
