This is actually a great illustration of the reason we have common carrier laws in the US.

Should we allow Cintra to let you go 100MPH instead of 70MPH if you pay a higher toll on the Indiana Toll Road? Maybe every 10MPH is an additional $1. Or maybe Cintra knows that Tesla drivers are rich, so their tolls could be set 10x higher than a Kia's toll. Or maybe people with Illinois license plates are on average more wealthy than people with Ohio plates, so they can pay more too...

How about free trips if you order more than $100 worth of food at Chili's? Discounts if you let them plaster your car with advertising?
