The U.S. Federal Fleet drove ~5 billion miles in 2015, the equivalent of ~120 million hours spent driving

According to U.S. Federal vehicle fleet data, vehicles owned by the federal government drove approximately 5 billion miles in 2015. The fuel, maintenance, depreciation, and leasing of these vehicles cost the feds ~$4.3 billion across ~640 thousand vehicles (including: sedans, trucks, buses, limousines, ambulances).

The stat that resonated most with me was the collective ~5 billion miles driven over the course of the year.

  • First thought–“that’s a lot of driving.”
  • Second thought–“that’s a lot of time spent sitting in a car, I wonder what all those hours roughly equate to in terms of employee (resource) time.”

The ~5 billion miles driven by the fleet equates to ~120 million hours spent driving, which is the equivalent of ~58 thousand full-time resources. Furthermore, this resource # accounts for ~2% of the total workforce employed by the federal government (~2.8 million), and costs the government about $6.1 billion in payroll and benefits each year.


As shown, I added a range of speed scenarios, but went with 40 mph as it roughly ties to a standard vehicle’s average speed over its lifetime. [U.S. treasury shows about 32 mph, but went with 40 mph to err on the generous side in terms of resources/hours spent driving]

The above is yet another example of how self-driving cars will impact the economy, freeing up the hourly equivalent of ~58,000 government workers in a given year.
