Those new headrests looks terribly uncomfortable with that sharp angle towards the head. I hated this in my M3 so I had to find an upper back cusion to support my upper back so my neck could be straight and not pushed by the headrest.
My two X' headrests are far more comfortable than the new "forward" headrest. I sat in the latest version this afternoon and sadly concluded that I will never buy another Model X if this headrest remains in place. Who the blank thought it was ergonomically proper? It reminds me of what Acura had in their MDX years ago and arguably were the least comfortable drivers seat I had ever tried.
Oh, well. Instead of buying a new one, I'll just drive my existing two for another 5-7 years.
