I watched the video on Youtube earlier this week.
My only thought was how on earth did Red Bull agree to their drivers doing this! The inherent danger of turning over a car because of the caravan began snaking was huge and to cap it all? Yep the cars were Aston Martin roadsters, so no protection whatsoever for the driver should they roll over! Multi million pound investment in drivers put in jeopardy and all for a chunk of advertising.
