Holy flaming car bomb, Batman!

Driving to work this week I saw not one, but two different vehicles blow their engines up. They were both trying to merge onto the highway when a giant cloud of white smoke busrt out behind them. Both vehicles kept going for a short way until the now huge cloud of smoke began to turn black. They both pulled onto the shoulder at that point. Fortunately my car runs off magic which is less prone to failure than those science driven automobiles my friends all drive.
