I think it would be hard if approached as a human technique automation, but there might be other ways to connect power and signal lines in a car in more mechanical ways. Depending on how much thought and desire has been spent by experienced factory designers...

You're absolutely right, and there's a lot of innovation that comes not from automating existing human technique but from changing how things are made so that the technique can be easily automated. For example: from through-hole components in PCBs to surface mount components in PCBs. Or even the PCB itself, which replaced wire wrapping (which, granted, can be automated) and soldering components together with free wires.

The design and the technique are critical variables that must be tweaked to make automation feasible.

Yeah, that's exactly the kind of shift I was thinking about. Now that said, I don't think Tesla is ready to do this, which would somehow prove old timers right. If Tesla managed to this bmw level of automation they'd be pushing enough cars to fulfill demands and keep investors. Later they'll make that 20% jump if Musk really wants to make a SpaceX kind of leap.

They are pushing enough cars, I think. One factory producing about 4000 cars per week is a very large factory, indeed!

I think Tesla is continually thinking of ways to improve the design, develop new techniques that can be automated easier. And I don't think these are all making it into the Model 3. Some will need to wait until the Model Y or even later. For instance, apparently the Model Y will ditch the 12 volt battery and feature a MUCH shorter/simpler wiring harness (which is one thing that's incredibly hard to automate, so making it simpler should help a lot): https://insideevs.com/tesla-model-y-ditch-12-volt-battery-95...

(with the caveat that Model Y plans seem to change each quarter)

from 1500m to 100m seems exciting
