An interesting stat here: 24 percent of urban ride-sharing customers use the service daily, primarily to avoid parking hassles and costs. Uber and Lyft, however, don’t reduce traffic. And people opt to walk less, which is a non-obvious cost of ride-sharing.
As ride-hailing has exploded in popularity, it’s caused a slight decrease in car ownership — but has also reduced use of public transit, biking and walking. The result is a likely increase in both traffic and the number of miles traveled in a vehicle, according to a national study of ride-hailing adoption from the UC Davis Institute of Transportation Studies being released Wednesday.
