I was very bummed on a recent trip to SF to find there was a waitlist for Waymo and I couldn't use the service! But I've since been 'accepted' so my next West Coast trip I'll definitely be taking a driverless car. I was a long time SF resident so I'll use my local knowledge to choose the most ratchet route possible.
The potential for self-driving cars to bring down the cost of rides is very exciting to me. I've been carless for decades and though I'm a huge proponent and user of mass transit, we have to be realistic. Most of this country is exceptionally ill-suited to mass transit and is custom-built for car traffic.
