jumps out of car

"What?" Susan exclaimed and guided her car off the freeway and down an exit ramp.
I felt around in the jumpsuit's tool pouch, until I came out with the little sports bottle with my second potion in it. "Just do it," I said. "Trust me on this one."
"Wizard," Tera said, her voice still utterly calm. "There is no one but you who can help my fiancée."
I shot Tera an annoyed glance. "I'll meet you where you hold your Cub Scout meetings."
"Harry?" Susan said. "What are you talking about?" She pulled the car down the exit ramp, onto a one-way access road.
"I understand what you're doing," Tera said. "I would do the same for my mate."
"Mate?" Susan said indignantly. "Mate? I am most certainly not his - "
I didn't get to hear the rest of what Susan said, because I grabbed my blasting rod in one hand, the potion in the other, opened the door to the car, unfastened my seat belt, and rolled out onto the shoulder of the road.
I know, I know. It sounds really stupid in retrospect, even to me. But it made a sort of chivalrous, cockamamie sense at the time. I was pretty sure that Parker and his cronies in the Streetwolves were shadowing us, and I had a precise idea of how dangerous they could be. I had to assume that they were even worse during the full moon. Susan had no idea of the level of danger she was in, and if I stayed near her I would only draw her more deeply into it. And Tera - I still didn't trust Tera. I wasn't sure that I wanted her fighting at my back.
I wanted to deal with my pursuers myself, to deal with my own mistake myself, and not to make an innocent bystander like Susan pay for it.
So I, uh, sort of threw myself out of the passenger seat of a moving car.
Don't look at me like that. I'm telling you, it made sense at the time.
I held out my arms and legs in a circle, as though I were trying to hug a barrel, and then scrape, scrape, rip, bumpity-bumpity-bumpity, whip, whip, whip, and thud. Everything whirled around the whole while. I managed, somehow, to keep my sense of direction, to maintain my momentum largely in a roll, and to angle myself toward the dubious comfort of the thick weeds at the side of the access road. By the time I came to a stop, I was among freshly crushed plants, all damp and cold from the rain, the smell of mud and gas and asphalt and exhaust clogging up my nose.
There was pain, pain everywhere, spreading out from my shoulder and my foot, whirling dizziness, blackness that rode on my eyelids and tried to force them down. I struggled to remember exactly what I had planned on doing when I had thrown open the door to Susan's car.
It came to me in a moment, and I jerked the squeeze top of the sports bottle open with my teeth and then crushed the plastic bottle, forcing the potion inside it out through the narrow nozzle and into my mouth. Eight ounces of cold coffee, I thought, dimly. Yum.
