Seating 100 and going 100 mph this “Torpedo Car” seems more steam-punk torpedo than car, and nearly as dangerous. The vehicle looks tremendously heavy, which makes the pylons and all other supports also need (and seem) to be very heavy duty. Also, a 10 or 20 ton bullet going 100 mph in a city and suspended 10′ off the ground seems as though there would be a lot of collateral damage to this invention.
