Exactly. Such a metric dismisses the traveller's view. It's a "pat yourself on the back" kind of metric. Reminds me of ... the often misused idea that more traffic lanes don't solve problem because they will soon enough actually be used by people who find a benefit in using them (the horror). One would hope for metrics that take into account the benefits to the travellers. A cab or similar is used because it brings a benefit to the user. NOT typically for the pleasure of spending more money.
