ET, phone home and ask: just what is this?
Elon Musk says he is going to blast one of his old Tesla electric roadsters into a Mars orbit so that one day it can be found by aliens. Maybe, while he's at it, he could also fill the spaceship with other things that seem to serve no obvious purpose. The Ronco Buttoneer, Sir Sinclair's C5, the BSB squarial, Tom Watson . . . oh, and perhaps the new Volkswagen Arteon.
