I recently bought a new car, and an amusing part of the test drive experience was figuring out how to start the damned things. Half the new cars these days have a smart key system with a plain power button on the dashboard, and it took me some fiddling to figure out exactly what other actions (pushing the brake, mainly) had to be taken to make that button actually work.

But you did, eventually, figure it out on your own and make it work. That's the whole point - 95% of people are pathologically unable to do that, when it comes to technology.
