What do you believe happened to Elle Driver?

the snake goes out of the van while Elle and Beatrix fights.
after she is left alone by Beatrix in the van, she curses, screams and cries for a few hours and then survives (her wounds weren't fatal). then she accepts what happened to her and continues her life as a blind woman. with no money and no relatives to take care of her, she asks the government's social security agency to help her, the government sends her to an institution (a nursing home) for blind people. she is taken care of there all her life, and dies at the age of 86...

After Beatrix left ler, she jumps out the window of the campar, got lost in the desert and died of thirst.

I think she will return in Kill Bill 3 and she will be Beatrix's final challenge (even though she's blind)

She suffered til her last breath. The trailers the coffin and if she ever got out of it past the black mamba she'd be travelling through the dirt. It's metaphorical karma to what happened to the bride.

When she got done thrashing around, she crawled to the front of the trailer. The snake bit her twice. She but the snake back three times. They both died next to each other not long after.
