I will say that Tel Aviv and Haifa both have excellent engineers. As Tesla grows I'd be a bit surprised if they didn't have engineers in Israel. That said, most of the engineering is still based out of Silicon Valley, so that might be why?

As a tesla fan and owner, I hope you get your superchargers. I've heard rumors that they've just started seriously producing the supercharger v3 hardware at the Buffalo, NY factory (Gigafactory 2), so maybe as that ramps up you'll be good.

Consider tweeting @elonmusk and asking. I did that for slow parts delivery and had the issue resolved in two days.
