10 Most Dangerous Concept Vehicles Of All Time – SlashGear

Swiss design studio Rinspeed has been responsible for some of the most outlandish concept cars ever to grace the auto show circuit, but none of them are quite as dangerous as the oddly-named Tatooo.com. The concept is not just a single vehicle but rather two, the main vehicle being a pickup truck with a crane in the bed. It’s a bit ugly, perhaps, but nothing life-threatening. The same cannot be said, however, for the motorized scooter mounted to the back of the truck, which Rinspeed named the Breathing Observation Bubble, or B.O.B. for short. Rinspeed’s press release describes it as, “a totally new diving apparatus,” since the scooter is designed to dive up to 30 feet underwater.

The diver is supposed to put their head inside the helmet that’s fixed to the body of the scooter, with the helmet trapping an air bubble so that the diver’s head can move around freely. There’s no mouthpiece, but rather a small bottle of compressed air that Rinspeed claims will provide enough oxygen in the helmet bubble for up to an hour of diving. Even for experienced divers, diving while having your head stuck in an unsealed scooter helmet seems like a very bad idea. The really alarming thing, however, is that Rinspeed envisions that “beginners” will also be able to use it. It’s best not to think about how those beginners would fare if the bubble bursts and they’re suddenly underwater without oxygen.
