I'm not certain the Waymo Driver has the concept of trains built in, but what if they did? How good is it? I applied at Waymo and found out they don't do well in the rain. What if they train is splashing up water in front of it? I'd like to know how it deals with falling rocks, which is a problem in California. Would they tell me or lie about self-driving, like some well known spoke persons do? What are the hackable weaknesses of Waymo? Have they tried to have visual and computer hackers fool the car and send it the wrong way? It just seems to me it's going to take awhile, maybe decades in my amatuer opinion.
