Another question is.. how does a well made car burst into flames so quickly.
There was a lot of discussion about various aspects of how cars behave when they crash, in a previous thread. But, speaking as a former firefighter, the tl/dr; is "cars do sometimes catch fire and burn when they crash". Hollywood style explosions don't normally happen, and car fires resulting from wrecks don't always happen, or even happen terribly often at all in my experience, but they are far from unheard of.
