It would seem putting buttons on the steering wheel is now a universal 'thing' for building a Hypercar these days; here are three different angles on the idea:
The Ferrari LaFerrari (TheFerrari) Ferrari.
I Like the simpleness of the P1; nothing is there that doesn't need to be, but I'm not sure about the electronic gauges.
The buttons on the 918's steering wheel look out of the way, yet important. This steering wheel definitely looks the coolest, like I'm in a spaceship from the future chasing down some aliens who stole all of the lead off my roof.
I really dislike the square shape of the LaFerrari's wheel.
