The main issue would be actually jumping off. I already get insane vertigo from being high up, so add that to the feeling of "I'm going to kill myself in 5/10/15 seconds" and I'm not entirely sure I wouldn't throw up and just run away lol.
Even if I did jump, the fear in those last 5-10 seconds of freefall is enough to deter me from it. That would be absolutely petrifying.
Then there's the fact that, if I did survive, I would be completely mangled. Unlikely but possible, so no thank you...
