Not as much as you are trying to make out. Let's see.
Last time you bought something at the grocery store
More and more meats and perishables are now shipped again across country via rail in intermodal trucks and refrgierator cars. Local distribution on both ends is the domain of the truck. Companies that make cookies, flour, sugar, crackers, snack foods and the like also ship their raw materials to bakeries, mills, and refineries and frequently ship finished goods out by rail too. Its quite rare for a bulk commodity like flour or sugar to be driven very far.
or filled your tank up with gas
Gas is shipped by ship and pipeline around here except for local distirbution. The ethanol being added to it is shipped by rail directly from the plant to the tank farm.
how do you suppose those items showed up in those places in an efficient manner?
Well, as I showed, frequently by rail, with only final distribution by truck.
That accountant
Don't us an accountant.
barber
My barber lives in the neighborhood. He walks to work from his house nearby. I walk to the barbershop.
financial planner
Don't need a financial planner. I can handle that myself with my wife's help (she was a financial planner, now retired to be a mom).
repairman
I'm the repairman around here.
etc that you use, how do you suppose they were able to get to work or show up at your home on a service call?
The one guy I did use walked on a sidewalk paid for with his property tax money.
How did they get the equipment and tools that they use?
Do you ever mail a letter or a package? How do you think it arrives at the final destination, sometimes clear across the country, for as little as $0.37. You depend on those highways whether you use them or not.
Letters I mail go by air if they are going cross country. Packages are mostly on the railroads in intermodal trucks or boxcars. The USPS mostly does not use over the road trucking except for short distances and of course, local delivery.
Oh, and I walk to the post office to mail my letters. Its on my way to work between my office and the train station.
