I’m afraid that would kill you.

Probably you would be hit by a car and killed.  Many animals in the wild sometimes choose to kill themselves, for example when food becomes scarce, but I don’t know of any human behavior where this is a common decision.  Sometimes we kill other humans, and sometimes other humans kill us.  In the early days of agriculture, before there were many domesticated animals, humans also occasionally killed and ate each other, although this is fairly rare now.

What would happen if I jumped out into traffic?
