Robotaxi companies Cruise and Waymo recently scored a big win when California regulators allowed them to expand their services and begin charging fares in San Francisco. But now the companies are hitting some speedbumps.

On the show today: Axios transportation reporter Joann Muller explains where we’re at with self-driving technology, why all eyes are on San Francisco, and who make the rules as robotaxi companies grow. Plus, the human-to-human connection that driverless cars are missing.

Then, Commerce Secretary Gina Raimundo is the next cabinet member in line for a trip to China. We’ll get into why the visit might be a little tense. And, some Americans are finding creative avenues to homeownership in spite of an unfavorable housing market.

Later, our listeners recommend some summer reads. And, this week’s answer to the Make Me Smart question comes from Mark Clouse, President and CEO of Campbell’s Soup.
