No. Keep in mind there is an elevator only at their
starting point. They
first have to choose their floor and then they cannot change floors. So they can't even get to the light blue area: they can only drive on one floor (which is quite small btw). Furthermore they can only move within the confines of the grey roads. So there is no way they can get to the light blue area if they started on the higher floor (the darker one).
As an aside: Also on the light blue floor no P has been chosen. So there is nothing to do there even if they started there.
