Cav was a bit too far back when it kicked off
He looked spot on, right on Philipsen’s wheel behind MvdP and then Luka Mezgec got between only to suddenly go backwards and let another couple get in front of him (Mezgec). So then Cav ended up four back from Philipsen instead of right on the wheel, and then had to come round the traffic instead.
We’ll never know if he could have stayed on to match MvdP’s acceleration and then come round even, but he’d have had a chance that disappeared when Mezgec pushed him out..
