How will they make sure not to have child mo-lestors give kids/women rides?
What will they do if they get sued?
Crazy people getting/giving rides?
Is there a place for complaints, both from the giver and getter sides?
etc. etc.
I am assuming you can rate the driver and customer so this will only be a problem for the first customer/driver, but still a problem. (what does Uber do?)
but I think there is a different problem the way this app works is good for Uber when the driver wants to make money and will go to the person's house and pick them up and then drop them down, but when this is a chesed I think it needs to be the other way around, the driver offering a ride and whoever wants could come to his location and get the ride to the address he is driving to.
