Chariot does not provide "modern, efficient transit" by any metric. They are commuter shuttles, operating only during commute hours. They're miles away from a transit system you can rely on for most of your activities.

Commuter shuttles have trouble attracting significant ridership, because riders are using them just for that: one commute.

We know that for transit to be successful, it's gotta be a way of life. For many car riders, their way of life heavily depends on getting everywhere with a car. It's hard to replace that with mass transit. Cities have done it, but commuter shuttles do not achieve that.
