Atlantis Anyone?

Underwater cars!...Ok! so we have seen all this in the movies, and now the movies are coming to life. Should we consider the writers and producers as Nostradam(u/as)ses. Did they really see this coming? Who should be getting the credit for these ideas anyway? 007 plates, nice!......so you get this car and decide to go for a swim with it, but who is gonna risk life and limb exposed to....umm...I don't know....SHARKS!!!! I would love to visit the Lost City of Atlantis and party with the mer-people and all...but at what risk. A company called Rinspeed built this underwater car (Squba), but has no plans to mass produce it.  I hope they don't regret that decision later like GM did with the EV1's.  How about an underwater gas station to go with that.
