Urban areas that allowed in the two ride-sharing services saw vehicle registrations per capita rise by 0.7 per cent, on average, between 2011 and 2017, according to research published in the journal iScience. Car-dependent cities experienced a larger increase. (The Logic)

Talking point: Jeremy Michalek, a professor of engineering and public policy at Carnegie Mellon University and co-author of the study, expected to see the opposite. “One possible explanation could be that there’s an effect on the other side, where somebody who was on the verge of being able to afford a vehicle now has an incentive to buy one and earn some money with it. So vehicle adoption by Uber and Lyft drivers may outweigh the effect of riders getting rid of their personal vehicles.” Researchers also found cities with higher incomes and fewer children saw a bigger reduction in transit use.
