There are 3,997,461 miles of roads in the USA. We plan on driving about 0.002% of them in one year. Of the 3,997,461 miles of total road miles, 46,837 are interstates. We will be covering 0.15% of those in a year. At that rate, it would take 666.67 years to cover all the miles of all the roads. I don't think it's feasible in my lifetime.
