I'd say steering wheels are "normally capped at 1"... although I recall one distinct occasion where I expected more two steering wheels, for driving training. Alas, it seemed the local school-district could only afford to put in an extra brake-pedal for the instructor, which did very little to help my anxieties.

So my first time behind the (singular) wheel and they told me to pull onto a major street next to the school, without even doing circles in a parking lot or anything. I guess they just expected most students had already done some illicit/private driving? Anywho, I had shaky legs when my turn was finally over.

Then I put an onion on my belt, as was the style of the time...
