It's not really like that at all. To begin with, a Roadster / model S is not a repurposed Toyota - and that is exactly why Tesla has succeeded so far. Further, they completely reworked those lines with a huge amount of new equipment, to the point that is was worth it to them to buy the robotics manufacturer. It is closer to a technicality than starting from scratch. And as far as anyone knows, a huge part of the bottleneck hasn't even been in Fremont, but at the gigafactory (which they also built prior to the 3) - with a supplier who they have since removed from the equation.
