Tesla is beta-testing its latest self-driving technology with a small group of early adopters, a move that alarms experts and makes every road user — including other motorists, pedestrians and cyclists — unwitting subjects in its ongoing safety experiment.

Why it matters: Tesla hailed the limited rollout of its "full self-driving" beta software as a key milestone, but the warnings on the car's touchscreen underscore the risk in using its own customers — rather than trained safety drivers — to validate the technology.

Tech platforms are no longer satisfied with debunking falsehoods — now they're starting to invest in efforts that preemptively show users accurate information to help them counter falsehoods later on.
