I think it’s fair to say that Tesla does a lot of big picture stuff right. There’s a lot of engineering cleverness designed into these cars - something that engineers hired by competitors to tear them apart have repeatedly reported/acknowledged. On the crash protection front, they took full advantage of having a different set of constraints to deal with than a vehicle with a conventional power train - and are reaping the rewards of better occupant protection. On the driveability front, they took full advantage of the packaging advantages of batteries (as in, you could put them down low in the chassis). And so forth.

I think it’s also fair to say that on the smaller picture execution front, Tesla has been learning rapidly, but still has some ground to make up (build quality issues and such).

If they make it through the growing pains and learning curve and get their execution/manufacturing/general ‘how to be a car maker’ stuff/keep you CEO from sinking everything with ill-considered tweets problems figured out quickly enough to remain financially viable, they’ll be a force to be reckoned with. If not, we’ll probably see a bidding war between companies with strong balance sheets, lots of execution know how, and a bit of a deficit in the electrification race to scoop up the goodies and use them to get a bit of a leapfrog thing going.
