Don't forget that public transportation can also be self driving and it will be cheaper than riding in a self driving car. So I don't expect public transportation killed, I expect self driving buses.
The recommended way of integrating reCAPTCHA v3 is to load it on every page of your site, not just on pages with forms. Given the popularity of this service, reCAPTCHA v3 is set to become a browsing history and behavioral data collector on a global scale.
Sites have brought this sort of thing on themselves by enabling (or directly engaging in) the abuse of users. That abuse forces me to take a very defensive posture when browsing the web. It's simply a matter of self defense.
If that means that I can't access the sites, whether it's because of recaptcha or other issues, then I won't access the sites. Easy.
Blocking trackers makes Google suspicious, so they're adding more and more recaptcha challenges to let me pass their tests, sometimes 5 to 10 in a row. I'm now working for Google's IA for free just to be able to make purchases online, access some services that I already paid for, or filling in support request forms (sometimes it's for websites operated by local communities and funded by tax payers).
I have absolutely no control over what Google does with all my recaptcha inputs, it could be to build a fleet of autonomous cars (that could end up killing the public transportation in my city), or improving an algorithms that helps drones identify targets during a social unrest (could be a future me).
Just because I want my privacy rights to be respected to the minimum (just don't track me for political/advertising purposes), I have to spend several minutes of my day working for Google and help them make money on advertising and sell AI to governments.
How dystopian.
