Tuesday’s column about the flood of Uber and Lyft cars on the streets of San Francisco triggered a tsunami of reader email and social-media outbursts. So I’m turning over today’s platform to my impassioned readers. The public is clearly reaching its tipping point on the out-of-control ride-hailing industry. The last time something like this happened, Airbnb cut a sensible deal with the city. So who knows? The boys-will-be-boys bro-ocracy at Uber might also finally accept some reasonable regulations.
