All of this has nothing to do with being an EV or hybrid.
I hope your reconsider:
Man was working on a hybrid and all of a sudden it went up in flames. If it was fuel you'd run away. But it was batteries. He got badly burned, his business got destroyed.
Most hybrids use NiMH batteries which are very stable; Toyota still uses these in current generation hybrids. But there is nothing in that video that tells us what caught fire. Many garage fires are started by people welding near fuel tanks which can easily start a fire. Others are started by fires in the interior when the welder fails to recognise that they've overheated interior materials. The biggest contributor to modern car fires, EV or ICE, is the interior materials - these are not required to be flame retardant like a sofa or bed is required to be.
Result is a massive medical bill, years of recovery, business that most likely will not bring money again. This is U.S.. No income, no way to pay for your house. You know what happens next.
Shit sucks, but that's nothing to do with the propulsion method the car uses, or used.
GD sound like you can have a coffee before you attempt to rescue yourself out, and firefighters can get there without lights and siren!
Yup, it does appear that EV fires propagate slowly, since the battery is well shielded from the cabin and vents to the outside; this presents far less risk than a conventional car where the engine is up front and the most likely contributor to a fire following a crash. Most people who aren't injured could self-extricate in the event of an EV collision that does start a fire. If they can't -- well, that's bad, obviously. But do we have any evidence that the situation is noticeably worse compared to the state of the art in ICE vehicles? Cars of all forms can catch fire following high speed collisions, it's an acknowledged risk.
It must be said that these conditions that can lead to a battery fire are rare and specifically designed out. Euro NCAP testing, to achieve high-star ratings, requires EV batteries to be monitored pre- and post-crash and no impact upon the battery can be observed; no thermal runaway, no voltage drop, not even leaking coolant. At the same time, electrical contactors or pyrofuses isolate the battery so that occupants can be cut out if necessary.
