The car with no user-serviceable parts inside
For the first time, a team of women is challenged to develop a car, and the car they come up with requires an oil change only every 50,000 kilometers and doesn’t even have a hood, so you can’t poke around the engine. To me, a car has no user-serviceable parts inside. The only times I have opened the hood is when somebody else said, “Hey, let me take a look at the engine of your car.” (I have a Toyota Prius.) On my previous car, the only time I opened the hood was to check the oil.
Sometimes the open-source folks ask, “Would you buy a car whose hood can’t be opened?” It looks like that a lot of people (including me) would respond, “Yes.”
