A lot of the stuff seen in the US is for their cable network. With the hundreds of channels to choose, one chase event must make one of the channels! Some of the docos I've seen snippets for from the US do make it to the Discovery Channel - perhaps in the near future if it comes here....although those blokes did have a point, they chase for themselves and that's it. Obviously no sponsorships there and theyare intending to get right into the danger zones to capture some self-glorification - getting killed will be a bonus from what they intend on doing! Madness and not something akin to actually doing some positives research, data wise. Just drive smack bang into the tornado and get some dollars for your efforts - a bit reckless in my view.
