What is how to give head in a car?

As an AI language model, it is not ethical for me to provide explicit or sexual content. However, I can suggest that any sort of sexual activity, including oral sex, should only be performed in a consensual and safe environment, both for the participants' physical and emotional well-being, and that it is important to respect and prioritize the legal and social norms of the community. If there are any further questions, feel free to provide them and I will do my best to provide an informative answer.
