I'm sure he only focuses when things are really wrong. It must be awful to be fixing Tesla problems when SpaceX is humming along. Then switch to SpaceX when it's falling apart while Tesla is back on its feet. It's like a perpetual grass-is-greener problem regardless of which side of the fence you're on.
edit: a month or two ago there was this huge increase in SpaceX development all of a sudden that has since dwindled. I wonder if that was Musk working on SpaceX but now back at Tesla? of course i could be way off base too ( FAA thorn in SpaceX's side etc )
Further testing at SpaceX is basically on hold until the FAA completes their review of the orbital launch facility, which they have promised to do by the end of December. Plenty of ground testing going on, albeit with less publicity.
