For all we know, her plan could have been to crash into a pole, in the middle of the parade (hoping for attention to her plight) and (as another poster claims) she didn’t see anyone else.
That’s a terrible plan!
But, like I had posted to another, no point in speculating about this, not enough information to be able to know what went on, so I am not making any judgment yet.
I’ll just say I feel very bad for those that died and their families.
