Of course cars are smelly, they are ugly, they get in the way and they can be fatal. But they are also beautiful, they are practical, they are a status symbol and offer freedom of movement. A car is something to dream about. Now so many dreams have been fulfilled that there is barely any freedom of movement to talk of. The roads are gridlocked and the streets are chock-a-block. With so many cars around it is better that we treat them as our allies.
