The article falsely assumes that the HOV lane has spare capacity. During rush hour here all lanes are equally clogged, and sometimes the HOV lane is actually slower than the other 4 lanes. The only way to fix LA traffic with current infrastructure is self driving car pools. If/when they can get to the point in which they are safer than normal drivers, and safe for the riders (crime inside of self driving cars) LA traffic will be solved. This will eliminate the necessity of having a car allowing for increased taxes on car ownership, reducing traffic on the roads.
