Most residents of our village are senior citizens who are mostly retired. And although they look financially secure, some of them bought a vehicle to drive and earn from it by using it as school service. They said that it's not really the money but the pleasure of bringing the children to school and back. But my husband is against it because it comes with so many problems particularly so that you are dealing with children. When one is injured or accidentally hurt inside the vehicle then it will be your responsibility.
People will get sick at times in the car but those types of things do not happen very much. It could be that people are looking for ways to be of service and with other people that make them smile and feel useful. As a senior citizen it gets harder and harder to find an activity that makes you feel wanted and useful.
As long as they get public liability insurance then they're covered if anyone is involved in an accident. Hopefully it won't happen.
