It's funny because most start times feel they've been shuffled around to accommodate US viewers, many start around 8a-11a EST. But on home turf, 3am it is!
I think FOM have got themselves in a difficult position because they wanted a night race for the spectacle (so much more important than the racing). But doing it on the western side of America makes it tricky time-wise for their biggest audience. The ultra-late racing is probably a compromise that'll please no one.
