I didn't say he was clever!

My brother has just put down a deposit on a new S and he wouldn't even try the autopilot on his test drive, he thinks the whole thing is mental.

I'm hoping to order an X later this year, will definitely go for autopilot but I'd use with caution.

Looking at the Tesla forums it appears that plenty of "features" like the music player are still in a beta state, so their approach to car building is like that of a software vendor.
