From research out of the University of Colorado Denver:

Ride-hailing accounts for an 83 percent increase in the miles cars travel for ride-hailing passengers in Denver's metro area, according to a study published this week in the journal Transportation by researchers at the University of Colorado Denver.

[...] For this first-of-its-kind study, the researcher-driver collected real-time data and surveyed passengers for feedback and demographic information. By surveying passengers, Henao learned that a combined 34 percent of his ride-hailing passengers would have taken transit, walked, or bicycled if ride-hailing hadn't existed.

Journal Reference:
Alejandro Henao, Wesley E. Marshall. The impact of ride-hailing on vehicle miles traveled. Transportation, 2018; DOI: 10.1007/s11116-018-9923-2

So, is ride hailing a net good, or not?

    1. Categorise new service as "vehicle miles", categorise alternatives to service as "not vehicle miles"
    2. [bleeding obvious] Use of service tends to result in less use of alternatives to service
    3. [basic maths] If n% of service users use alternatives less, vehicle miles increase as a result, for any n>0

    Conclusion reached without surveying any passengers at all. Wonder how much was spent on this that could have been spent doing something useful?
