If the coefficient of friction is the same on both wheels, both wheels will spin. If you were in a clean parking lot, chances are that was the case since both wheels were on the same, clean type of pavement.

Go put one wheel on gravel and one on pavement and see what happens.

The real issue comes when turning, as you put more load on one tire than the other which causes more traction in that tire, and results in the inside wheel spinning.
