Tesla CEO Elon Musk admitted in an unusually tense conference call last week that he doesn’t have a site confirmed to launch production of the Model Y crossover, but he’s confident (as always) it’ll start making the car in 24 months. By all accounts, it’s an aggressive, if not insane, timeline.

Anyone who follows Tesla has known for months that it has . Musk said as much in the call last week, saying Fremont is “jammed to the gills,” which left many to wonder, where, then, will the Model Y be built. Or why hasn’t a site been selected yet?

Musk said a decision on the Model Y site location could come by the third quarter of 2018, and would happen no later than the end of the year. When that happens, surely he’ll deliver some sort of splashy announcement to coincide with it, as is customary for Tesla. And then he’ll have to figure out where to build the and .
