Quick quiz: What percent of 2016 vehicle miles traveled (VMT) in the United States came from ridesharing? Given the hype, it would be reasonable if your estimate were higher than the right answer—1 percent. Currently, ridesharing does not apply in any significant way to the overwhelming majority of practical use cases. Car ownership is still more economical and convenient for most car owners and users, and for all of the buzz and excitement, when we count VMT in absolute terms, ridesharing’s share is almost a rounding error.
