I find it interesting the only honk came from that group of white cargo vans that seemed to be trailing the motorcade…. all the same van… that could mean they were with the motorcade…
I counted- this van was one of 6 identical vans in that motorcade. After it passed and honked, more in the caravan followed. Whoever honked is definitely part of whatever event those cars were traveling to.
could have been a grip driving a van full of cables for all we know. Whoever it was was deemed important enough to have ambulances and armored trucks and security SUVs behind them
