What would happen if there were no cars, buses, trains, boats, or planes? How would this change your life?

My car is the main asset that I have. Without it, or any other mode of transportation, getting around and getting to class and work would be so much more difficult. I feel like I would be a lot healthier however, because my only other option would be to ride a bike, scooter, or skateboard. I would also be a lot more tired. My work is 34 minutes away without traffic via car. If I were to ride a bike, it would take a significant amount of time longer to get around, like several hours opposed to half an hour. I am very grateful to have a car that runs and to have some other mechanical mode of transportation if my car were to break down.
