Here are some of the things that can go wrong:<p>1) some teen drivers are not allowed to drive at night. Some people have a suspended license and are legally restricted to only driving to/from work or to/from school. These people might not be able to participate. How are the restrictions added to the system?<p>2) My timing is tight. Work ends at 4:00 and I have to pick up the kids from day care by 4:15. It's a 10 minute drive. Do I schedule a pickup every day or do I chance that I might be required to detour for someone else?<p>3) I live in the countryside about 10 minutes drive from the nearest neighbor. Do I get to have my own car? If not, how long does it take to get a ride?<p>4) I live on an island where the ferries to the mainland only run during the day, and I want to take the first ferry of the morning. How do I arrange a 5am drive if there are no cars on the island, or none close to me? What if there was a storm that prevented the ferry service from running the previous day?<p>5) Does the scheduling system know the ferry schedule well enough to know if a pickup is even possible? What if I and the car are on the ferry going from A to C, with a stop to load/unload at B, and there's a notice for a pickup at B. It's not possible to unload, pickup, and load in the short time the ferry is at the harbor, and the next ferry is an hour later. Am I penalized for declining the ridiculous assignment?<p>6) I do social work and visit 12 residences each day. If I partake in this system, will it introduce enough variability that I have to reduce the number of home visits I make?<p>7) I am moving and the car is full of boxes and luggage. (It took an hour to load everything.) Do I still have to pick up other people?<p>8) I suffer from social anxiety disorder and have difficulties dealing with strangers, including as a driver or as a passenger. Do I still have to participate or is there an ADA exception?<p>9) I have a restraining order on me which prevent me from being within 1,000 feet of my ex-spouse. I'm scheduled to pick up someone from next door to said spouse, and that address is well within the exclusion range. What do I do?<p>What is the resolution process should there be a conflict between what the system expects that you can do, and what the reality is?
