> The Model 3 has potential to shift the whole market if they can provide a practical electric family car for the average people living in suburban areas.

I actually don't think the target audience is families living in suburban areas. That's not the target audience of the BMW 3 series or Benz C class. I think their target audience is young professionals who can't afford a car that quickly costs over $100k but care about driving a practical, electric, professional car.
