"Wait until you see the real steering controls and system for the 3. It feels like a spaceship."
I've seen a lot of speculation about steering wheel shape and control buttons and paddles. That's so yesterday.
I'd love a sidestick, just like the controls on spaceships or modern fighter aircraft. Left, right, throttle, brake, all in one hand. Complete and total drive-by-wire. Yes, it'd make it more challenging to drive while texting with one hand and holding a cheeseburger in the other (I use my knee and cruise control in that case), but it sure would make those long-distance drives a bit easier - place the arm on the adjustable armrest, grab the stick, and go. With modern feedback techniques, it would be zero effort - the "centered" position with no forces applied would tell the car "keep doing what you're doing" - steering, braking, speed, etc. You'd only apply force or displacement to change something.
That also provides a convenient yet subtle place to put buttons and switches. Look at a modern Gamers joystick, with 15 or more controls available with no more than a slight movement of the finger. There's no longer a need to try to tastefully integrate 15 different buttons on the giant, glaringly obvious design element shoved in your face; instead they sit down out of the way at the end of the armrest.
I no longer need to be able to slide past the wheel on my way into or out of the car; the drivers seating position is just as easy to get into as the passengers location. I no longer need to adjust the front seats to be able to set the distance to the pedals (or adjust the pedals) to be comfortable; I just need to be able to adjust an armrest. For those tall drivers, you get an extra 6-12 inches of legroom because you no longer need to leave room for the pedals.
The dash is now completely opened up for the designer - there's no need to place lights, gauges, controls where they won't be covered for the 90% of drivers. I don't know what you put there (and in reveal #1, it wasn't clear that the designers knew either) - but it's a giant blank slate that the interior designers get to be creative with.
And the car is handicap accessible for many from the factory and off the lot.
I like it!
