HOT lanes

Access to car pool lane at a price. Using an existing HOV lane to use its capacity instead of building a new toll lane saves money. But if the HOV lane gets too congested, would it not encroach the rights of carpoolers?. And why have been the chosen ones at some time? Is a favour protected by law? In this article 'time is money' for someone. This reminds me of parking situation at our apartment. At all the apartments that I have stayed at before, covered parking was free for the first car. At this current apartment at first it was 10$ for covered parking and now its 15$ for covered and 5$ for open spot. The thinking must be for some renter 'Shade is money'.

In HOV lane, concept of reversible lane is interesting.

Since HOV is first to reduce traffic by encouraging carpooling as one of the methods, it is fine to have high occupancy toll lanes as long as their speeds are maintained.
