There's the big sign there telling you to go to arrivals for drop-off. This is probably a stupid question but can Waymo cars interpret those temporary display signs and follow them? Would it?
It seems to handle the standardized ones (think "construction ahead, detour left") perfectly well from the rides I've taken, but there's all sorts of ways they could be 'cheating' on that.
I'll be honest, I think LAX's traffic is better than SFO's.
It feels like there's a lot less spaghetti at LAX, the shortcuts are reasonable, and you don't have separate international and domestic loops.
The Big Dig, for all the digs it rightfully got for taking forever and costing a shitton, actually does the job it's supposed to (mostly). I'm generally pleasantly surprised how few problems it had when I lived there.
I haven't driven through it much since it was completed - I moved out of Boston in 2005. As a now-just-visitor I find driving through the central artery tunnels even more stressful than on the old elevated 93, but that could just be a lack of familiarity thing -- I don't drive when I visit Boston, only if I'm flying in to Logan to head to the cape or something. It is, however, _really_ nice not having the freeway cutting through and the greenway is gorgeous.
I'll take JFK over LAX. The construction going on right now at JFK sucks, but LAX is comically bad. Just last week I was on a rental car shuttle at LAX and watched 3 separate groups of people at different terminals miss their flights because traffic just wasn't moving.
