Zipties are all over the place in any modern car. They are used especially to hold wiring and hoses securely so they don't flop around and abrade against other parts of the car.

Why? If the fastener works, what is the issue? This is the exact sort of thinking that compounds into large delays.

In this case, Tesla obviously ran into an unexpected problem, and did not have a part to fasten this piece. They used various fasteners to secure it, and I'm not aware that anyone has had any problems with it, except that it seems strange.

At the time, Sandy Munro saw something similar in his tear-down, and didn't think it was a big deal. Obviously not a permanent part, but nothing to be worried about, either.

This is the kind of fix you can get with a recall or late problem. It's not a "zip tie" it's a steel cable tie. The wood's a bit shonky but another manufacturer might have got plastic clips made instead of the wood and otherwise made exactly the same fix.

I don't think zip ties and wood are a structural part of the car. It look like it was just there to absorb vibration when they ran out of the foam or plastic part. Not great, but hardly deserving of all the criticism that it is getting.
