A person agrees to go to -some event- with me.

If the person changes their mind, before entering my car, and I then force them into my car and drive them to -the event- then I have kidnapped them, and I have committed a felony.

If the person enters my car, then half way to -the event- changes their mind, and demands that I take them home immediately, yet I continue to the event, then I have committed no crime. They may be angry with me, they may never speak to me again, but I have not kidnapped them. They abandon some measure of control once the journey has begun.

I wouldn't go quite that far. Your passenger has the right to leave your car at any time and place on your route as she sees fit, provided only that it is reasonable and safe for you to stop the car there. She does not have the right to damand that you take your car on a substantially new route. If she indicates a desire to go home, and her home is not on your current route, I see no legal reason for you not to continue to your current destination and let her catch a cab (or bus, train, etc.) from there. Courtesy would suggest that if you'll be passing a better transit point than your destination you should offer to drop her there, but if she doesn't request it I see no obligation on your part to do so.

On the other hand, if a woman demands to be let go immediately I see no legal basis for keeping her in your car any longer than traffic and road conditions require.
