LA, let Uber's cars share the road

[Commentary] Consumer protection is important. And rules to ensure safety and to deter fraud are necessary. But many regulations aren't about safeguarding consumers; they're about entrenching incumbents (at consumers' expense), and they're typically created by the very agencies that are supposed to oversee those incumbents. Governments at all levels should guard against this tendency by prioritizing innovation and removing unnecessary regulations that burden risk-taking entrepreneurs. If regulators took this approach, we'd make it easier for creative start-ups like Uber, Lyft and Sidecar to be competitive. And we'd leave fewer consumers standing, literally and figuratively, at the curb.
