If you start digging into statistics, LA hasn't been getting all that much value out of its public transit investment. Using 2009 and 2019 as base years (partially because 2020+ are screwed up because of the pandemic and partially because that's where I can actually reliably source data quickly), the LA metro area went from 6.2% mode share in 2009 to 4.1% in 2019. NYC increased from 30.5% to 31.6% in the same time frame, and most of the other US cities-with-decent-transit posted similar small inclines (DC being the big exception, but this decade saw an epic meltdown with WMATA, so that's to be expected).
