Hi wpowers,
I'm sorry to hear you had such a frightening thing happen. I haven't had anything that scary happen while driving but I do have an alter that just "decided" she was going to drive. First of all a different alter is in charge of driving already and second this alter who decided to just up and drive didn't know how and also didn't need contacts.

I hope you can talk to the alter who scared you and let them know how upsetting it was for you.
safe hugs ((((((wpowers))))))
