Put her in the trunk

You pull over in a small side road with a small wood thicket blocking the view from the road. Your mom looks at you confused and says. "I´m not getting out naked here Jim, people might see!"

You smile slyly: "Oh no Mom, I don´t want you undressed. Yet. I want you to get in the trunk, I promise to drive home carefully as always."
"But what if I run out of air?" She responds. "I´ll open the small hatch in the backseat, you won´t **** at all."
Your mom is still unsure bit reluctantly gets out along with you and opens the trunk. As she gets in you remember the emergency handle on the trunk. What if she pulls it and signal for help?
