That's not the point. If you really are a solipsist, why would jumping off a cliff have more probability of leading to death than not jumping (because the cliff doesn't really exist)?
All solipsism says is that you can't be sure reality exists outside of your own mind. You can question whether or not you would be dead outside of your own experience, but you'd still be dead in your internal world.
The only reason to believe that jumping off a cliff leads to death is because that's what we observe happening to other people and we assume we are like other people. But the solipsist has no reason to believe this as the other people don't exist outside of his own mind therefore he is not like them.
"But the solipsist has no reason to believe this as the other people don't exist outside of his own mind therefore he is not like them."
Except the solipsist is also unsure he exists outside of his own mind too, so why would he believe he is the sole exception to everything he's observed in the only reality he can be sure of?
No? How does him being unsure that reality exists outside his own mind mean he believes he's the sole exception?
I mean if you're unsure there is a reality outside of your own mind, wouldn't that make you more risk adverse? Your death could potentially mean that everyone you've ever known/loved would cease to exist, even if they are a product of your unconscious mind...

A solipsist isn't "unsure", he definitely believes reality doesn't exist outside of his own mind. That alone sets him apart from everyone and everything else in the universe, because a solipsist believes he is the only one who actually exists.
