Strongly disagree. If you mimic the established user interface of the car people have been using for generations, then it should behave like people expect it too. If special qualifications are required to drive it, then you should sell it only to those who can prove them. You cannot build something that looks like an elevator, has buttons with numeric labels, and when people push one button the doors close and they find out they just selected the power setting of a giant microwave oven. I mean, you can build it, if you don't care about people getting microwaved.
