Contrary to the people in this twitter thread, I absolutely hate this. I don't want a car with parts that are held on by glue.

I think you may be associating “glue” (or epoxy in this case) with an inferior type of fastener. Modern glues chemically bond the materials, forming a much stronger adhesive than physical fasteners ever could.

If anyone would like a simple demonstration of just how good modern adhesives are, go buy a decent wood glue (not even an epoxy!), some wood, and test the strength of some glued joints. With the exception of butt joints (flat edge to flat edge), 99% of the time the wood around the joint will break before the joint itself. With a quality glue or epoxy, even butt joints can be stronger than the parts they glue together.

In some situations, industrial grade structural adhesives can even be stronger than well made welded joints, which is literally just heating up the metal so it can recrystallize into a single lattice.

You’d hate to find out how your windscreen is held in place.

I'd hate to find out the hard way.

Heh. I was once driving on a highway when my hood latch broke. My hood flipped up and folded over the windshield, blocking all view of the road.

Scared me to frigging death. I was going about 45 mph at the time. Stuck my head out the side window and maneuvered to the side of the road, and then pried my hood back into place and tied it down.

You know that new car smell? That's the smell of all the glues they use.

You'd be surprised how many of your car parts are holding up with glue.

Have fun on your WW1-era dune buggy.

This is one of those, leave it to the professionals moments.

There are tons of types of glue, think of super glue being a weak form of glue compared to alternatives (TDI + polyol)

you're going to have a bad time in the future, cars are moving from welds to adhesives. https://www.nytimes.com/2016/08/12/automobiles/the-superglue...

Agreed, though not because of the glue itself so much as the entire concept.

It looks terrible. It literally looks like nothing more than what it is - a cheap plastic knob glued to a touchscreen. Made to look even worse by having an empty center exposing more touch screen.

Add to that, I don’t see any reason why a volume knob is any more or less deserving of a physical control than climate controls or radio station presets. That is to say, volume controls are plenty deserving of a physical knob, but so is everything else you might do in the center console with similar frequency.

Which is to say, further more, that they are admitting that physical controls are better for frequent adjustments like volume, but instead of handling that properly, they’re just saying “here’s a big touch screen for everything... but we’ll relent and give you this lame ass pasted on knob for volume and volume alone”.
