While ride sharing offers many benefits, there are also some challenges: - Scheduling Conflicts: Coordinating rides can sometimes be difficult, especially if appointments run longer than expected or if there are changes in the schedule. - Availability: In some areas, there may be a limited number of volunteer drivers or ride-sharing services, making it harder to secure transportation. - Comfort and Safety: Patients may have concerns about the comfort and safety of ride-sharing vehicles, particularly if they are dealing with severe side effects or have compromised immune systems.
