LS is not a bad car by any stretch, and there are many things about it that I really like... especially the interior. But it's really foolish to launch a flagship luxury car and then before it's on sale, show a Toyota product with Apple CarPlay. I am still struggling with powertrains as well, with reports of the 500h being choppy and unrefined in real world driving, and the TT V6 delivering lackluster acceleration and performance numbers. On top of that, it's the biggest LS ever and has less rear seat room than a Honda Accord. These are a few things that, IMO, show this car was an 80% effort and could have used a little more development time.
LS back seat vs design was conscious decision by Lexus, that has nothing to do with time spent developing it. Hows TT V6 delivering lackluster acceleration? Wasnt it fastest vehicle on MT test, on their track?
LS does not exist in a vacuum, CarPlay will come in next MY, when it is ready - first Toyota to have CarPlay will start sales in 4-5 months. I have read a hundred reviews of Tesla and only last week I learned that they dont have CarPlay or Android Auto in any of their vehicles.
Apparently, Lexus LS is leading the charge for Lexus in Japan, brand sales up 68% on LS500 and LS500h sales, so "someone" likes it. They sold 4400 LS's in 2 months, making it their best selling model in Japan, with next best NX having 50% less sales.
Edit: we can see sales data here:

Google translator works good enough to get the info. They announced 9500 orders in first month, back in November. Sales goal is 600 (it will come down to that in 2nd or 3rd year).
