Elon Musk unveils how cars can be transported through the first test tunnel in Los Angeles and gives some test rides.

The Company has abandoned their previous plans of using "electric pods" to transport a vehicle through the tunnel and instead are planning now to use "tracking wheels" that would have to be installed to the car.

So far this has been only tested on a Tesla X for obvious reasons. Even though Musk emphasises that other car makers could use this installation too, there are more restrictions to the car itself.
