I don't see why they wouldn't be able to charge him, sure you don't want to be sitting around on youtube all day trying to find people doing stupid illegal stuff just to charge them, but there were so many points that escapade could have ended very badly that it's ridiculous. If you're going fast enough to catch that much air over a rise then you're going fast enough to not have a clue if anyone is right in front of you just over the hill. I bet that since they apparently had several calls in, this video simply provides evidence for a series of criminal actions that were already being investigated, rather tahn being the sole reason an investigation is opened.
