Is that second screen infront of the passenger ONLY for displaying that swoopy pattern? Because that is really dumb. Or it more likely is just a backlit pattern, but still, seems annoying for long journeys to have that shining at you.
I drove all the big luxobarges (LS-L, S-Class LWB, 7er L, A8L, XJL) back to back a few years ago (2014 model year) and the LS was easily the worst one. The biggest thing that killed it for me was the UX. Between the UI on the screens, the infotainment controls and the driver controls, it was just awful. Didn't improve much in the 2016 RX I drove a few months ago, so I'm not holding my breath for this one either.
