How many drunk drivers have already been in collisions that would not have occurred had a sober Uber or Lyft driver been driving instead? The city's ridesharing ban is creating more risk than it avoids. 

I agree with the premise that people should not drive to bars. If we really cared about the hazards of drunk driving, we would subject everyone leaving the parking lot of a bar to a breathalyzer. Clearly, society in general isn't concerned. Those who are most likely to drive drunk are among the least responsible, so it's a bit short-sighted to hope that drinkers will be proactive.
