you forget just how much plastic is present under the hood of modern vehicles.... and how hot plastic burns. hot enough to melt aluminum - which the bodies and hoods of Expeditions are made out of.

Modern DOT 4 brake fluid, engine oil, Automatic Transmission Fluid, and power steering fluid, is all highly flammable as well when heated. the brake fluid reservoir burning up would dump burning brake fluid unto the pavement and ignite nearby tires and anything else flammable - tires + wheel well liners alone will burn for hours. Power Steering lines and reservoir would do the same.

Fuel lines also remain under pressure for days after parking a vehicle, all vehicle fuel systems have some 'soft' line that could burn thus spraying a small amount of pressurized gasoline out further spreading the flames onto more plastics like bumper covers, foam bumper inserts, plastic grilles... no external fuel is needed as vehicles have all the fuel ready to go to burn for hours.

....i work on Corvettes and Camaros in my spare time and race often so I sorta know what im talking about if you havent surmised. Racetracks take fires very seriously for this reason. a small underhood fire will destroy an entire vehicle if left alone. Every racer knows this. this event is no different.

also you are incorrect about who travels in what. The Presidential motorcade consists of mostly armored vehicles but the secret service does lots of travelling outside of the motorcade to secure the routes and places scheduled to visit and this travel is best done incognito so as not to tip off any threats. AKA in civilian vehicles and not in large convoys cause anybody can spot 3 identical black Suburbans with government plates and tinted windows and know the feds are rolling in.
