function driveVehicle(veh, x,y,z, velocity=0.1, gpsmode=false)
check if x y and z are numbers, check veh is element
if gpsmode try and use an export using the gps resource to get the road map to drive and use velocity variable for setting velo.
if not gpsmode, or no export then just rotate veh and drive directly, which in that case probably hit a wall
end
