Yes, it is possible for someone to have both a car and a bike. Many people own both a car and a bike for different purposes. They might use the car for longer distances or when they need to transport more people or goods, while they use the bike for shorter distances or when they want to engage in physical activity.
On the other hand, it is also possible for someone to have neither a car nor a bike. Some individuals prefer to rely on public transportation, walking, or other means of transportation instead of owning a car or a bike. It ultimately depends on an individual's personal preferences, lifestyle, and transportation needs.
