Fortunately, I haven't run into one of these Waymo cars yet but they're coming soon.
From the site Joe linked to —
From Union Square to Serramonte Center, get around in an all-electric Jaguar I-PACE, with no human behind the steering wheel. With over 2 million rides served and tens of millions of miles driven, we’re proud to provide safe transportation in the city we call home.
Download the Waymo One app and ride today.
Even though there's "no human behind the steering wheel", I'll betcha a cookie that there's still a spot on the Waymo One app that suggests a twenty percent (or greater) tip.
And then I'll double-down and bet that there are people who DO leave a tip for the 'driver' of an autonomous vehicle. -"BB"-
Yes, I suppose I could agree with you ... but then we'd both be wrong, wouldn't we?
