If you can get more than 50% of people to understand what your thing does just from the name I'd say that pretty good, actually. Literally no one is turning on Tesla's auto pilot with no information on how it works beyond the name.
Not many people would literally declare "I confidently believe that airplane autopilot is a turnkey solution". But perhaps the point is that a lot of people would vaguely feel that way without exactly crystallizing it as a thought. And those vague feelings would be what the branding is seen to be playing off.
I fall into this trap so many times. You know in your logical brain that what you see isn't a good enough sample for any kind of statistical significance but at the same time you keep seeing things that every other part of your brain reckons is significant.
Like I see Belgian drivers driving terribly every day and I'm pretty certain that they're much worse than British and German drivers in every way. But the only statistical thing I can go back to is the number of deaths [1], which could include other aspects rather than just stupid driving.
My brain wants to shout out that their's clearly a problem, but that 'clearly' is only on the stretch of road I see. It could be that Belgian drivers are really good everywhere else in Belgium.
"Less than half" is way too much.
