* Country/Region: Commuting distances and car ownership rates differ significantly worldwide. People in sprawling suburban areas of the US, for example, will likely spend far more time in cars than those living in densely populated European cities with extensive public transport.
* Lifestyle: Someone who commutes daily for a long distance will spend far more time in a car than someone who works from home and rarely drives. Frequent travelers also skew the average higher.
* Age: Younger people may spend less time driving due to reliance on public transport or ride-sharing, while older people may spend less due to reduced mobility. However, middle-aged individuals often have the highest car usage due to family and work commitments.
* Socioeconomic factors: Car ownership and usage patterns are influenced by income levels.
Studies have been conducted in specific regions, but a global average is difficult, if not impossible, to definitively state. You'd need to specify a particular location and demographic to get a more meaningful answer. Even then, the figure would be an estimate with a margin of error.
