I think they are talking about OnStar, the GM product that provides in person concierge service in additional to vehicle maintenance information and crash reporting. The connection to leasing they are trying to make is likely to say, by installing OnStar they can monitor how the user drives the car. However, the math behind leasing and payments etc is known upfront. When you return the car, they don't just say "Well you owe us an extra $10,000 because you accelerate hard."
