“It does suck, because everybody kind of makes fun of the Cybertruck. To the outside person, it’s kind of weird, it’s ugly, whatever. Once you actually get in it, drive it, you realize it’s pretty frickin’ cool,” he says. “It’s kind of been sad, because I’ve been trying to prove to people that it’s a really awesome truck that’s not falling apart, and then mine starts to fall apart, so it’s just… Yeah, it’s kind of unfortunate and sad.”
Good points.
Why aren’t they using fasteners? Cost or weight?
Probably cost, via speed of assembly, robots are really good at depositing glue, also design and safety, since the glue can remove intrusive hard points in a car. Also rigidity could be improved since the glue is continuous vs spot welds or fasteners.
I recently glued the roof skin on a classic car I’m restoring and the reason for replacement was that the 60 year old seam sealer had failed 20 years ago and the rust had crept in between the spot welds. I used 3M panel bond, partly because spot welds were difficult to do in position and it would likely be more reliable and water tight long term.
I probably won’t be around to find out if it fails, at any rate.
