I remember Clarkson talking about how much time he's spent with Hammond and May as oppose to his kids. Plus a January/February season splits the year in two nicely.
Exactly.
Blame Top Gear Live aka their money milking cow.
Given there are fewer stops on the tour this year than there were last year (three cities on the tour instead of six), I don't think it's that simple.
IMO, they all came to the realization that they couldn't have another year like 2009, which was pretty insane with all the side projects they had going (moreso in regards to James and Richard), meaning they didn't finish filming stuff for S14 on time, there were the November TG Live shows happening as S14 was starting...and the toll it took on them showed in the episodes very much (moreso during S14 than S13, I think). The guys were just worn out from being stretched so thin, and most of S14 was pretty bad overall anyway.
With extra time off between Series 15 and 16, the trio can have a bit of a breather, and they'll have more time to give us fans a quality product.
was kind of hoping they'd rock up to an empty Acer Arena, have one of those

moments and figure they should make more Top Gear episodes instead.
They won't be rocking up to Acer Arena anyway. Sydney's not part of the tour this year.
So much for that plan .. 6 episodes for the whole year
Would you rather have one solid six-episode series and two specials at the end of the year, or one excellent six-episode series followed by a mostly lacklustre eight-episode one?
