SXSW isn't typically on the circuit of mobility-related events, but this year we went to participate in our partnership with Wards Intelligence and C3 Group's Smart Mobility Summit. Doug Newcomb of C3/Wards joins the show to explain why the Austin confab is such a good place to discuss new mobility matters, followed by a conversation with San Jose mayor Sam Liccardo about leading one of Silicon Valley's major metropolitan areas into the autonomous era. Liccardo suggests that AVs are replacing decades-old investments in light rail, setting off a lively conversation about how cities should allocate scarce transit resources.
