Are you suggesting the cheerleader should be raped instead?
No.
I was being very tongue in cheek. Since a cheerleader getting into a stranger's car is one of the many trope setups for porn. And usually ends up being consentual sex.
The real reaction someone should have is:
1. Confusion.
2. Ask who they are and why they're in your car.
3. React appropriately to the reply.
If the reply is 'I'm gonna kill you unless you drive', you drive.
If its 'oh shit, wrong car' then wish them a good day and talk about it later as a funny story.
In no world should you get out of your car, walk up to theirs after the mistake, and try to kill them.
