[From the department of irrelevant stuff…]
Like many Norwegians, I have a Tesla (it is a bit like owning a Volvo station wagon here, due to enormous tax breaks on electric cars.) I am very happy with it. Elon Musk got rich on Paypal and took some business concepts from that experience, including a referral program: If a Tesla owner refers someone who buys a Tesla (my referral link is here, hint hint), the new Tesla owner gets a $1000 rebate and free supercharging as long as they own the car. And that is a nice thing to give away.
But what is the referral prize? I did not know, but no someone I have referred has bought a Tesla, and it turns out I get a Radio Flyer Tesla electric toy car. It not only looks like a Tesla S (down to the charging cable), but also has a frunk and you can connect a music player to its sound system(!).
Oh, to be four again… On the other hand, Lena and I will be grandparents in a few months, so it will see some use.
