And speaking of electric vehicles...
The 4wd/Offroad/Truck section of the show was in the new West Hall of the convention center. It's quite a walk from the South Hall (where Jeep is) to the West Hall but to make that easier Elon Musk's Boring Company provided a solution (yes, that's the real name because their business is boring tunnels). There's now a tunnel system running between all the halls and transportation in the tunnel is provided by Tesla SUV's. I rode it from the West Hall to the Central Hall.
There's a display on the dash showing the surface map and where the Tesla is under the surface (the red triangle in this image):
The Tesla's have a driver for now but I hear the plan is to implement autonomous Teslas in the tunnel in the future.
Pretty cool.
