To fix L.A.'s traffic, we need tolls
The true solution to LA traffic will never happen.  And that solution is buses.  But not the current underfunded system that barely limps along. A massive number of buses, like 5x the current number.  And combined with tolls for cars to get cars off the road.  The large number of buses is critical because it greatly reduces wait time between transfers.  It also allows adding express bus lines between major areas.  But buses have a really bad reputation in LA.  They are trying to build more rail which doesn't have the bad reputation, but that will always have the last mile issue.Since the bad reputation of buses will likely never go away, it seems rail + uber pool/lyft line might be an alternative.  It won't be as good, but could be good enough.  I wish there was a company other than uber/lyft which focused on just this first/last mile issue for rail.  Or maybe the metro here could just start a service like that themselves.  Something like Rail Pool to get people from/to the rail stations.  It combines the best of both transports (the rail covers 90% of the trip, the extensive road network is used for the first and last miles).
