It won't shock you to hear that Tesla low-balled demand for the Model 3, but by how much? Er... quite a bit, actually. Elon Musk has revealed that his company expected "1/4 to 1/2" of the pre-orders it got (252,000 worldwide as of this writing) for its first semi-affordable electric car. While he'd expected lineups at Tesla stores, he figured that there would be "maybe 20-30 people" in queue at a given shop -- not the hundreds that showed up at some places. As a token of appreciation, Tesla plans to give those in-person customers an extra reward on top of what every pre-order customer will get.
