Before leaving both PRE-OP WAITING ROOMS, the user will have to select a VEHICLE from a pop-up window.
Possible vehicles are a wagon, a car, a motorcycle, and a wheelchair. Dr. Gillerman pointed out that the vehicles
available to infants/toddlers and school-age patients are not the same, so we'll need to find out which vehicles are
available to whom and present a different vehicle selection based on which PRE-OP WAITING ROOM the user is in.
Once the VEHICLE is selected, it drops off the bottom of the screen and then the "dashboard" of the vehicle rises
from the bottom of the screen until it lines up with the NAVIGATION BAR. The rising of the dashboard will give the
user the first-person view that they're sitting down into or getting down onto their VEHICLE of choice.
