From today's a[er ... USATODAY.com - More airports try to keep drivers out of the loop. The article reports on parking lots at airports designed for people picking up passengers, who are no longer allowed to wait at curbside. So drivers wait with cars in lots, and when the passenger calls on the cell phone, the driver can pick up the passenger. An interesting intersection of information and communication technology and transportation.
Since I live 20 minutes from the airport (MSP). I have people call when landing, and by the time they pick up their luggage, I am outside. The synchronization is pretty good, though the airport cops do try to move me along, I am usually sufficiently stuck behind other pick-up drivers that there is no problem. MSP does not have a cell-phone lot, I guess we are behind the times and need to close the cell-phone lot gap.
