This really depends on the definition of a 'crash'. For example, fatal accident > insurance claim > minor incident.

If we use insurance claim as the definition then: - The average driver files an insurance claim for a car crash about once every 17.9 years [1] - The average driver drives 13,476 miles per year [2] - This means one insurance claim per 241,220 miles driven by a human driver.
