If you’re like me, when you see a Tesla on the road you sort of have to squint to tell the Tesla Models S and X from the more common—and cheaper—Models Y and 3. This irksome game may have just gotten easier, because Models S and X are being killed off. Eagle-eyed Tesla watchers may have noticed that Models S and X looked like they were in trouble last summer when Tesla stopped taking orders in Europe. The soon-to-be-discontinued Model S is the oldest model actively produced, having been around since 2012. Musk is essentially telling investors not to be sentimental about outmoded ideas such as Tesla being a car company.
