If you've never been inside of an assembly plant, it is an absolutely amazing experience -- especially when line is running.
Here are the front and rear windshields being installed by fully automated robots in a Ford F150 at DTP a few years back. This was my truck being built.
Hahah you guys should see the F-35 fighter assembly line at Lockheed in Ft Worth, TX. It’s over a mile long, nowhere near as fast moving as these videos and a lot more hand done (there are reasons why). Been there a few times and it’s amazing every time I go!
