A concept car, primarily a track car I think. I would think less than 10000 will be sold but some of the tech will make it into other models over time and the tech could be interesting for military application. Jumping Humvees like cars anyone?
So in the straight of Hormuz, you'd have a "Tesla boat" hover off a destroyer and into the water, reach the target as a boat, then hover up to its deck. People would exit and meet the vessel's crew for however long. No hook ladders, anchor lines or helicopter rappels. Seems like a good balance between projecting soft and hard power to make a ship turn around, arrest or replace crew, run security checks or extract payment. The Tesla boat should make this type of rendezvous less costly, easier and safer - legality/ethics considerations aside.
Would be interesting if the boat rose up on a variable foil and keel as well where the forward thrusters could be used for super speed, maneuverability and fuel efficiency. I am just dreaming.
