Just a silly question...

I'm 180 cm tall (6 feets) and driving the back of my head rests on the upper part of the seat (just above its 'hole'). Is it correct or is my driving position too upright?

In other words, is the 'hole' in the seat designed for the head?

In that case to fit my head in it I have to make love with the steering wheel

 

the hole is actually designed for the helmet. if you need a headrest, Rick's sells an aftermarket one that is nice... but a bit pricey IMO.

and what you do to the steering wheel is your business, but I usually only touch it with my hands.

 

At 6'3", I'm not even close to the hole. There would only be a range of height (torso length) that would allow the head/helmet to fit there. Taller folks won't fit and very short folks won't, either.

I'd say it's just a styling treatment...
