A lot of cars to destroyed in car accidents every year. If you assume ~50,000 fewer totaled cars per year that&#x27;s a lot of extra miles.<p>Also, several cars have made 1+Million miles as I the odometers roles over.  Considering many people drive less than 8k miles per year that&#x27;s a lot of driving.<p>PS: The real issue is both age and driving reduce value.  But, age is automatic as soon as you know the cars model year so people care about high vs low mileage because they are already buying an old car.
