I believe that’s Ivanpah Lake, which is on the California side of the border.

Anyone can drive out there. Easy access from the truck stop parking lot, assuming a truck hasn’t parked in front of the dirt road. You just pull off the interstate and take a rip across the lakebed, fast as you want. Though it’s a good idea to check that it’s thoroughly dry first. In addition to a heat mirage hiding surface water, there’s a hazard of the surface being sun baked dry but it being muddy underneath the crust.
