First doors on both sides open. Then the passenger-side door closes. Then the driver gets out to look at what's going on.
Meanwhile, the lead car has gone away and there is nothing (shadows, wailing siren, nothing) to indicate its return. Also, the next vehicle in line just sits there - no doors open, nobody gets out.
There are soooooo many things wrong with that operation that one has to wonder if Obama was driven out another way in a Smart Car while nobody was looking and these goofs forgot to act as if the Prez was actually inside the limo.
stay safe.
