Not short sighted but afraid of losing even more money than reported. When these car companies operate on razor thin margins when even a small disruption to sales put them in the red by billions. This is why they get *sugar* PE ratio multiples and deserves it.From what I'm getting, on information from Asian sources... there's really not a "chip shortage" per se. It's just how cyclical things are. Usually companies (carmakers in this case) make their orders (or their OEMs) to chipmakers/foundrys on a quarterly or yearly basis. As covid kicked in, they started cancelling orders left and right. From chipmaker's perspective, they were like... "ok, let's get the production shifted to those who didn't cancel". This is important for TSLA because they might be those few ones who didn't cancel their orders and march along.
Fast forward to 2021, the economy is recovering from covid and carmakers are realizing that without those chips that they canceled, they weren't going to match their production rate. So, they all rush to foundries like TSMC for their chips to be made. However, TSMC and other were already producing at 100% capacity. And there isn't much they can do because chip productions are very difficult/expensive to ramp, so it's carefully calculated so that it always runs near capacity. Thus, a sudden "comeback" of canceled orders that were supposed to be part of a 100% production planning is what's causing the "shortage". It's just there's only so much production, and the carmakers lost their chance for chip production.
If they want to blame on anything, it should be blamed on their own short-sighted vision.
