If this is trivial to you, what do you consider moderately difficult? What's sufficiently difficult that you have to spend a single day thinking about it? How about an open problem requiring careful planning and months of effort?

It's like the word "trivial" has no meaning anymore. All I can tell from people using it these days is that they're very confident in what they're about to say.

What I consider non-trivial is tangental to comparing the cost/benefits between autonomous driving and ride share services. The non-trivial part of this is [nearly] solved, as is evident by this Waymo soft launch.
