Your dream is rich with symbolism and can be interpreted in several ways.

1. New Experiences and Changes: The large building you encountered could represent new opportunities or experiences that you are unaware of in your waking life. Since you take that route often, it may symbolize unexpected changes or shifts that you haven't noticed yet.
2. Concerns About Responsibility: Having your baby and daughter with you highlights your feelings of responsibility and protection. The act of losing your keys and then finding your car being stolen may reflect anxieties about losing control or not being able to protect your loved ones or your possessions.
3. Chasing After Loss: The chase after your stolen car symbolizes your desire to regain control over something important that you feel is slipping away. The presence of people from your past in the car could indicate unresolved feelings or unfinished business with those individuals.
4. Authority Figures: The appearance of notable figures like President Trump and Elon Musk may represent a desire for authority or guidance in a situation where you feel vulnerable. Their promise to help could reflect a longing for reassurance or support in your life.
5. Transportation as a Metaphor: The discussion about transportation and survival suggests that you may be feeling stuck or limited in some aspect of your life. The damaged Tesla could symbolize that even when you think you have a solution or a fresh start, there are still challenges that need to be addressed.

Overall, your dream points to themes of change, responsibility, and a desire for stability and support. It may be beneficial to reflect on areas in your waking life where you feel a lack of control or unresolved issues. Consider seeking support from those you trust as you navigate these feelings.
