From the way you presented that, it looks fake and staged.
However, rest assured, it is true. This event is normally occuring in the vehicle. It has nothing to do with bot events.
According to the changelogs, the time in which the vehicle burns on fire after being destroyed is extremely short, and the explosion force is very powerful. This combined with the fact that vehicles respawn immediately upon destruction by default is the reason why it keeps doing this. The vehicle is destroyed once, and at the same time it is destroyed a replacement is spawned, but not before the old one is finished burning. Because of this the newly spawned vehicle is destroyed by the explosion of the previous one and continues on like this in an endless loop.
Here is the changelog to confirm it:
MAS Swarm Fighter v1 to v2:
(Actually it's more like V1.5)
- Edited model. (reduced ploy-count/lag)
- Window lighting should be better (should no longer become extremely dark)
- Bullets now fly faster and do more damage
- Max speed reduced slightly
- Reduced turning speed slightly (first attempt at making the fighter easier to control)
- Reduced health slightly
- Added 'after burner' effects (trail effects)
- Modified tire/hover effects
- Modified final explosion effect
- Final explosion effect now slightly more deadly
- Reduced burning time (player now has less time to jump out)
- minimum PlayerRunOver speed increased
The things I have bolded are the things responsible for this happening.
If Army Unit notices this, he can simply just increase the burn time and lessen the explosive force to fix this.
