Your stat is too narrow and misses a lot of important factors. It's better to just use a stat that summates all of them, such as the average cost of a new car.
The average new car today costs about $48,000 [1]. The average new car in 2010 was about $24,000 [2]
Average of what? All of car models available? All actual cars available to be bought? Cars that are actually sold, not just sitting in lots like Teslas?
