Just look at those coursing streams of speed lines, and their resulting explosion. That's how you start a goddamn comic book! It certainly doesn't end there though. People get wrecked, giving Black Jack the opportunity to reattach limbs:
Children get run over:
A guy gets vaporized by a train:
Even the doctor himself gets in on the action, using his car to take out some punks:
And sometimes we don't even see the crash, but just get to witness the gruesome results:
It's pretty crazy, a great example of Tezuka's ability to work cool stuff to draw into stories and make them exciting. It will certainly be something to watch for in future volumes.
