<span>There is 50% that your car will catch fire in a serious collision. This is because of the impact of two solid things due to the collision which creates friction. When there is friction, then electrons will be excited that causes heat energy to produce. When there is heat energy, the tendency for it to catch it near the fuel is big that is why some cars burn or explode.</span>
