Anything that can't go on forever eventually stops. After years of bumbling-to-sinister city rule, Toronto finally reclaimed its political power and voted in a new mayor, Olivia Chow, a progressive of long tenure and great standing (I used to ring doorbells for her when she was campaigning for her city council seat). Mayor Chow announced that she was going to reclaim the city's prerogative to limit the number of Ubers on the road, ending the period of Uber's "self-regulation."
