Trips towards Barrie South GO

Generally it's a 15-20 minute direct ride towards Barrie South GO to catch a connecting Southbound train to Toronto Union Station. The application doesn't prioritize the 3 passenger pickups to be all headed towards Barrie South GO.

I've been in many close calls where for example 2 of the 3 passengers are headed towards Barrie South GO, but the application will pickup a 3rd rider that's going somewhere that isn't Barrie South. This is inefficient routing, and we can see how much the town pays Uber (15-20 dollar subsidy) for potentially a service that isn't practical.

Perhaps the solution is to reserve a ride the night prior. Or switch to dedicated On-Demand Transit for GO Station routes specifically?
