Assessment

Transportation statistics and mobility research consistently corroborate that typical passenger cars spend roughly 95% of their time parked. According to the U.S. Department of Energy and Federal Highway Administration's 2022 National Household Travel Survey data (published in August 2024), household vehicles in the U.S. are driven an average of 64.6 minutes per day and parked for the remaining 95.5% of the day. This aligns with UK RAC Foundation studies (2012 and 2021) finding cars stationary 96% of the time, Donald Shoup's foundational analysis finding ~95%, and international data from the UITP and MIT Senseable City Lab showing ~95% to 96% idle time.

U.S. Department of Energy / FHWA Fact of the Week #1356 (August 2024), analyzing the 2022 NHTS, found household vehicles were driven an average of 64.6 minutes per day, spending 95.5% of the time parked.
RAC Foundation reports ('Spaced Out' in 2012 and 'Standing Still' in 2021) showed typical cars in the UK and England are stationary/parked 96% of the time.
Academic studies from Donald Shoup (2005), the UITP Millennium Cities Database (95.8% parked), and the MIT Senseable City Lab consistently estimate private vehicle parking duration at approximately 95%.
