Any photos of these slick vehicles you could point to?
I also shouldn't oversell them, the ones I've seen look 'slick' in that they are similar to other well-polished LIDAR test vehicles that aren't just a bunch of sensors bolted to a roof rack, and they're 'mysterious' in that they're unmarked.
They're Lexus' with mattresses on the roof.
Ghost has a weird pattern and their name on the sides of the vehicle. Nuro is uses Prius' mostly. Woven planet/Toyota tends to have slicker looking vehicles. They're the right vehicle in this picture:
