I'm not sure that the earlier plane post is related to the New York Trip, but I could be wrong. Here's what has me curious:

A) Obviously not the same person in "shotgun" - not the same vehicle either. I'm not sure what procedures are in place, but I tend to think that VIPs only ever transfer from plane to suburban to hotel, and so on… but I'm not privy to any security plans

C) I'm not seeing an S Class anywhere in the motorcade… although I've drawn a line to the closest possible match. Personally I don't think Q's pic and its foreground subjects traveled with the motorcade, unless its an advance car or otherwise acts as spotter?

B) I found this interesting - I can be completely out of order, but there are 4 irregular "flecks" which to me look like they are on the surface of the vehicle and not a reflection. I don't think they are impact hits as there doesn't look to be any concavity distortion or dimpling in the door skin. Its just very odd to me, because I've never seen a motorcade vehicle not immaculate with a VIP in it. Was there an incident? Everyone looks calm, so I'm guessing everything's OK, but why would Q mention out of the ordinary what a good job the detail did? I hope this is helpful.
