Musk appears to be on the verge of making his robotaxi vision a reality with a test run of a small squad of self-driving cabs in Austin, Texas, that began Sunday with customers paying a $4.20 flat fee! Reaching a million may take a year or more, however, although the billionaire should be able to expand the service this year if the Austin demo is a success. The stakes couldn’t be higher, nor the challenges. Rival Waymo was busy deploying driverless taxis in Los Angeles, San Diego, Austin and other cities by using a different technology that allowed it to get to market faster. It just completed its 10 millionth paid ride. Musk says the robotaxis will be running on an improved version of Full Self-Driving and the cabs will be safe. He also says the service will be able to expand rapidly around the country. His secret weapon: Millions of Tesla owners now on the roads. He says an over-the-air software update will soon allow them to turn their cars into driverless cabs and start a side business while stuck at the office for eight hours or on vacation for a week. “Instead of having your car sit in the parking lot, your car could be earning money,” Musk said earlier this year, calling it an Airbnb model for cars.
