True, however there's a lot of jobs (particularly in final assembly) that just can't be replaced by robots. One job near mine would for sure be impossible for a robot to do.
Have you considered a C-Max energi? It's not much bigger dimensions than the Focus and the battery is packaged a little bit better in the back (unless you want to put a stroller in it lol).
While I agree that 3 years is a little long to wait (at this point probably more like 2 by the time it actually launches), I understand why. Ranger is the more important product, Bronco is just incremental so Ranger is going to get the priority.
several well placed sources have said they're using the '73 Bronco as inspiration.
As to when we see it is a little clouded. NAIAS 2018 is a good guess to see a concept at least. PremierDrum mentioned several months ago that he had heard Mules would be out on the road around September.
