You analogy would make more sense if you added the word 'performance' to the statement. A car is fairly intuitive to drive. Driving licenses are required for safety. The comments you make are akin to performing in a sports car, where concentration and accuracy is key. You car analogy would fit if you had PCs as a F1 car and tablets as a Mini. F1 car is for speed and requires perfecting to get the tyres working right. A Mini, you can pretty much drive through all sorts of faults and be none-the-wiser, because performance just isn't an issue. Well, 90% of the time. :)
