Requires a good mix though. The parent is still correct. Mythbusters spent a long time trying to get cars to blow up in a dramatic hollywood fashion in various episodes and determined that under most conditions it wouldn't happen.

They did get it to happen, they just had to try really hard.

In most accidents the gas tank will not blow up.

High velocity accidents where the gas is quickly dispersed into the air is pretty much the only way that happens.

All of which are symptoms of burning, not explosion.
