It's easy to give up on a car that hasn't been driven in anger yet and has only completed "sub system" testing WITHOUT the wings or downforce package that the car will run in races.
With all the negative posts on Mclaren, seems Mclaren is only the one who's got confidence in their car, they haven't scrapped it yet and by the looks of things continue on their plan to run THIS car in races and contend for the Championship with it.
IMHO- Lewis AND Button couldn't be on a better team....and Lewis shouldn't leave F1 to Nascar until he's too old to drive F1, what's Schumi's, Barichello's age again?
