Imagine a simple scenario. Take your $260,000 Helix to the grocery store to pickup groceries. While you are in the store a mother fighting with her kids accidentally damages your Helix backing up the car. Are you going to hop into that thing even with what might be considered minor damage? Probably not because you would not know how to evaluate whether it is safe.
A car. You'd just hop in to determine if it is drivable.
