Problem: when my friends and I take a trip with more than 1 car, it is difficult to keep both cars on the same route and with the same stops.

Potential solution: the abality to send a link that would sync up our drives to be able to see where they are on the route in real time. If the future route changes, the device that did not initiate the change would be able to accept the change. If either car gets off the shared route, a notification would be sent to both users and the user who is behind would be able to start a route to get back on the same route as the other drivers.

Additionally, there could be a follow me function where one vehicle is able to follow another without putting in a destination.

Finally, backseat drivers could add stops rather than having the driver enter it in.
