It would be great that if Waze can help the customers to advise a meeting place for people who are trying to carpool.

Basically, its taking 3 routes, if there are two participants are trying to get from their places to the same destination. .
1. Person 1's route from place A to place B.
2. Person 2's route from place C to place B.

Then, Waze can calculate the most close meeting points fro Person 1 and Person 2 to meet and get to place B.
