I get around by bike, foot, transit, and car in that order and have mostly lost my ability to not get motion sick in a car when I'm not driving. I prefer taking Waymos any time I'm not in a hurry in SF, but usually traffic is bad enough during the hours I take it that it's not a huge factor anyway and if you can get a MUNI that's close to your start and end points, it's significantly faster. Rideshare and taxi drivers in most of SF are constantly changing lanes, cutting off pedestrians, or speeding from light to light to try and make up the extra 10-15% time lost that Waymo eats and can make for an unpleasant experience for me, but yes if I'm in a hurry I do prefer a human driver.

(There's a slight component where as primarily a cyclist I feel that Waymos are much nicer to cyclists than human drivers are and it gives me affinity to Waymos that I don't feel for human drivers in the city.)

I find Waymo the most useful to take after a concert far from a MUNI stop because usually surge pricing makes Lyft and Uber really expensive and I'm usually tired enough to not want to walk to a stop or it's late enough that MUNI headways are far apart.
