For 5 (Autopilot) it is definitely more useful in certain situations. Long distance road trips? It's a god-send. We often drive to Montana (~600 miles each way) and autopilot does 99% of the driving. That said, tons of cars come with "lane keeping" now days so that specific feature isn't unique to Tesla.
