^ as true of dtla, improvements to LAX have come so slowly that patience in LA is a requirement & necessity. But better late than never.
Most airports throughout the US & world have had ppl mover trains, some airports even having them for decades.
I watched this vid a few wks ago & as true of other aspects of LA, it doesn't help the image of the city. At least widespread homelessness isn't a big embarrassment to LA, so there's that.

But I agree with you about the blue version of the trains vs the white ones. I think the ppl mover at the getty museum is very sleek looking, but the all white trains apparently slated for LAX are kind of iffy.

I don't know whether public officials like Eric garcetti deserve either praise (for the good things) or blame (for the bad things) for what's occurring in LA. Probably 50/50.
