No I just think it's dumb to expect everything to be bubble wrapped and idiot proof. Instead of tempting fate and expecting something to be safe, just don't do those things. Same idea as not putting your hand on a hot stove.
- I would totally agree with you if this was for some reason the *only* way the thing could work, but it's obviously not since so many other people have designed it differently and it's not some massive national crisis that automatic doors are not closing cause something is in the way.
It's like if someone designed elevator doors to close and the elevator to move *no matter what was in the way* (like those, you know, horror movies)
A stove cannot cook things without getting hot. The stove top is not generally a surface a person might rest their hands or be expected to handle while in use. You also do not immediately get 3rd/4th/5th degree burns accidentally touching a stove either. Not a great example.
