Lexus 430
I remember quite a few years ago that the Lexus 430 sports car with Mark Levinson sound system was advertised as "A great sound system with a car attached" (or words to that effect).
This is just a ruse to clog the streets with more unwanted furniture, distraction and adverts. Nothing whatsoever to do with erecting a useful-to-the-public amenity. A moving billboard with a phone attached.
