Despite the fact that our show is pretty much the opposite of careful, we discuss precaution, regulation, and institutional choice with Sarah Light. The environmental and other effects of Uber and Lyft are complicated. If they’re very hard to calculate and understand, how should we regulate them to address their harms? With uncertain webs of causation, can the precautionary principle tell us not simply whether to regulate but who should regulate? Sarah thinks so.
