I don't quite see the purpose of illuminating the entire tunnel unless they're using their autonomous driving tech which uses a camera. If so, they've just put a single point of failure on their lighting systems.

To show it off, obviously. It would be silly of them to use self driving tech when theres already solution on the market. See: https://en.wikipedia.org/wiki/List_of_automated_urban_metro_...

It makes sense in that it:

- reuses technology Tesla have already developed and are familiar with

- increases sales of said tech

- a controlled setting where they can get more data about real-world performance of their tech

- introduces their tech to punters
