This enables the vehicle to continue to be driven (at reduced speeds, typically under 55 mph) for limited distances (up to 10 mi depending on the tire/device).

Roadside assistance works, but waiting an hour with your principal in the car is not the answer. Similarly, changing a spare if also not ideal given those circumstances.
