We can view this as either a positive for how Uber works or a negative for how taxi cabs work. If the pervasive means of transportation other than ambulances are unresponsive or expensive compared to ambulances, then obviously ambulances are the choice. One might also drive oneself, get a ride from a friend or family member, or hope that a city bus will be fast enough. An Uber ride could be faster than a ride from friend or family and safer than driving oneself.
