I doubt many in LA are aware of this.
Wilshire is L.A.'s densest business and residential corridor, and it's among the city's biggest traffic nightmares at rush hour, which is why devoting a lane in each direction to bus use only is a good idea. More people already travel by bus than by car along the route during peak hours, and a fast bus lane would lure even more out of their cars, reducing pollution and radically reducing commuting times for bus riders.
Lots of people use the mass transit system in LA that lots of other people are basically unaware of. It's interesting.
