Hell, the fog light body panels on my partner's Audi Q5 was press-fit. We found out it was held in with a couple plastic tabs after it went missing (presumed stolen) and we had to replace it.
Even better, should it ever fly off, the plastic covering would do less damage than the Cybertruck's heavy steel body panels.
What other manufacturers glue large steel panels on the sides of their car?
Sure, some other car makers use glue and tape to adhere some parts of the car together. Usually things like plastic trim pieces, not large steel panels.
It's a long steel trim piece. Calling it a large panel seems misleading. Similar (but not as long, as far as I know) pieces are glued by other manufacturers but they are plastic.
Many other manufacturers secure some exterior trim pieces with glue or tape.
