Well, it sounds exciting anyway. 
But this is really unusual for the circumstance. Give it about one and a half minutes, then the horn starts to blow as the flaming vehicle somehow seems to come to life and then crashes into a building while the horn continues to blow intermittently.
Very bizarre, unless a mechanic can possibly explainâŚ
Never tore a steering column apart per se, but if the stops for the shifter were plastic, once they melted I could see it dropping into gear. Confused why it was idling unless they just left the whole shebang sitting as it was after the incident for safetys sake (IED). The horn is just wires intermittently touching after the insulation burnt off. Pretty funny how it went from âBAHAHAHAâ to âOH SHITâ. roflmao
Iâm guessing the TTP after this will include a brick in front of the tires.
It always amazes me about the totally weird shit that happens on this planet, day to day, or in combat. If you didnât have a battalion of witnesses, photographic or video evidence, no one would ever believe itâŚfunny shit!
My guess is that the e-brake was on and the thermite/fire cut the cable.
On a slight downward slope gravity took over.
Agreed. But, the lights coming on and staying on while the horn blows so intermittently is kind of weird. The horn pattern sounds more intentional than like two wires simply touching. The first time it happens the car isnât even moving let alone bouncing. 
I an sure it is explainable, just odd and interesting to watch all these things somehow happen at once.
