Women do not frequently travel alone in Mexico, including driving alone on the highways. Walking on the street could net you a catcall, and walking alone at night is not advisable except in well-protected tourist areas. I've known people who have had uncomfortable experiences in crowded places such as subways. In general, though, Mexicans are extremely gracious, and will help a woman carry heavy items, open doors, and provide information, among other courtesies.
