The two cars in front are part of a fleet that are available to subscribers of the service. Montreal has several car sharing services. While I don't use them, I know many who do. I do own a car, but use public transportation a fair amount. I love the concept of a sharing society - but know, that in some cases, the developers of the sharing ideas (e.g. Uber, AirB&B) are earning loads of money providing the means to share.
