SB50 allows for 4 and 5 story apartment buildings near "high quality" bus routes. This is a not the same thing as just allowing development near transit stations. If you look at a map of LA almost everything qualifies for development.
You could at least read your own link before spreading FUD. The increased height limits only apply to the rail / ferry stops (i.e. the green areas). The bus routes and jobs-rich areas get density requirements waived (i.e. you can create one story condo-complex), and reduced parking limits, but there is no change to height limits in those blue areas.
