Multicrew: you cannot be in the SRV or deploy a SRV in multicrew. For this reason, if you want to make a multicrewed run, the SLF pilot must wait until the SRV section is over before joining the ship.
Yeah but ... what if the multicrew pilot was sat at the military installation in Gridge 1, then the guy in the SRV does his SRV run, rejoins his own ship and then immediately multicrews for the guy at Gridge who then flies the rest of the race? I'm guessing this ain't allowed (i.e. the SRV driver needs to be the multi-crew pilot, he can't be the co-pilot)?
