Tesla is reportedly planning a reveal of its self-driving robotaxi on the Warner Bros. lot amid widespread anger in the industry over the brand’s controversial CEO, Elon Musk, resulting in a rejection of its cars.

I remember seeing reports that Tesla models outside of the cybertruck have tanked. Goes to show which assholes are still clinging to this turd of a brand. Btw I saw that the panels above the door are glued to the body. Lol
Enjoy your shit cars folks.
It’s honestly quite sad to see what the brand has become. I have a model 3 that I got back when elon was just weirdo that smoked weed on rogan’s show and made sophomoric sex jokes. My car is a solid vehicle that feels fun to drive. There were a lot of really talented engineers that built a great product. I’d never buy another though.
What is the problem with glued panels?
Well for one glue breaks down at borderline random amounts, could last one year could last a hundred also imagone if one came off going 70 on the 15.
Adhesives are used in many aerospace applications to bond panels and structural elements. Some Lotus racing and street cars chassis are bonded aluminum! Lotus are racing chassis specialists, making chassis for other racing teams.
The space shuttle’s bottom tile heat shield, which withstood insane temperatures and stresses, were glued.
Adhesive science is pretty cool. You may want to read up a bit.
Take a look here. I’ve used their adhesives and 3M, also an impressive range, in a signmaking business I used to own. Not a single sign has failed in decades, weathering rain, snow, wind, very hot summers. We are talking pretty big surfaces, under pretty big loads and stresses.
Im vague aware though my interests lay with metallurgy and old pieces of tech, these two kinda feed into eachother. Anyways my point shouldve reflected moreso on the fact that Tesla has shit build quality that makes the Ford Pinto look like an M1 Abrams in comparison, do you really think they are using decwnt quality adhesive for their vehicles?
I think the engineering is probably mostly sound. I don’t trust the execution. Many adhesives need specific curing times, temperatures, UV lights, whatever. If you don’t respect those…
That’s my concern. Application/execution, not design. Let’s remember that Musk believes in advancing by BOOOM
I find your post very cool but I still have skepticism about the application of adhesives here, specifically because they seem to be used on this truck in many places where they don’t need to be. Why use an adhesive over a fastener? In my mind, you generally wouldn’t.
Also I think signage is a decent comparison to an automotive application but it isn’t a perfect one. You’re basically comparing a mostly static load scenario to a completely dynamic one. It’d be more akin to the aerospace example but even those adhesives are in a very different use case. These cybertruck adhesives have to last 7+ years of thermal cycling and dynamic loading. If these adhesives hold up over time, I’ll be very impressed.
There are many reasons to use adhesives rather than fasteners. A very basic one is that fasteners weaken the surface where the drill is made, and all the forces are borne by the fastening point. With adhesives, forces are borne by the entire piece. How’s that for a neat trick?
Another advantage is that you don’t see a rivet or screw head on your nice shiny surface.
I never said signage was a 1:1 comparison with automotive, just that I’ve installed a lot of signs, some very large, whose structure was made of bonded aluminum, that many are over a decade old, that some withstand major stresses, and that none have failed.
As to the longevity? Do you often hear about planes losing panels? Because there are a heck of a lot of bonded panels in airplanes, both commercial and military.
Also, probably somewhere in your cars there are some bonded surfaces.
Lastly, Lotus has been making their sport scar chassis mostly bonded aluminum for the past, what, 30 years, maybe more? There is not a single case of delamination in those years. Good enough for me.
Is that the glue that Tesla is using thought? Are they applying it correctly?
