Please be aware that China is actually really good at automation. If you don't think so, look at your phone.
Automation is great, but its expensive and time consuming to design custom production lines, so in most cases, it requires volume. Good manufactures do manual where it makes sense and automation when it makes sense. Tesla is learning this lesson right now.
The problem with Zero is that Zero has zero volume. Other industries would laugh at Zero's volume and that means that Zero does not have a lot of buying power. I'm sure some of Zero's parts are off the shelf, but I don't think there is much volume there either.
What I want in 2019 is for Zero to increase it sales, make a profit and improve their company - better service, better reliability, lower prices, more models and accessories. I don't know, but based on Zero's cash injections last year, I don't think they are profitable yet. I've heard former employees say that they need to double there sales to break even.
I think tariffs are stupid. They may protect a American job that his hanging by a thread, but I don't think it would get one back.
