Speaking of Jolyon Palmer, he hasn't been out yet in this session. Just the Briton and Kevin Magnussen to make an appearance on the track in second practice.

Lance Stroll runs wide at Turn 4 - the same spot where Jolyon Palmer obliterated his front wing - but doesn't hit the big bump of a kerb with quite so much force and gets away with it. Stroll is currently 15th quickest with 1:21.466.

Sebastian Vettel, Danil Kvyat, Romain Grosjean all head out to join Kimi Raikkonen on the track as the Finn sets the first time of the session - a 1:20.085.

Max Verstappen's number one fan is at Hungaroring. I tracked him down at Silverstone but didn't ask what was in his Max bag. Missed opportunity.
