This is the dashboard of a Tesla S:
With a large touchscreen and very few physical buttons. A lot of design time went into building this. Very cool-looking.
This is the steering wheel of a Formula One racecar (which is incidentially the whole user interface of the car):
A small screen and a lot of physical buttons. A lot of usability engineering went into building this. Very useful.
If you are going to be handling controls while driving (whether at 55 MPH or 200 MPH), you need tactile feedback from the control you are operating. Tesla opted for cool, Formula One opted for useful.
Are you building technology to look cool or be useful?
