There are good features in 2016 that may benefit from a tweak for 2017.
Pit lane speeding, change it to a 5 second stop and go penalty if under 5 KPH over limit, drive through if greater that 5 KPH over. Will still stop people from dive bombing the pits but won't totally destroy your race if you just miss the limit.
The ability to rejoin the race if disconnection occurs is great but having the AI controlled cars circulating around the track if there is no chance of rejoining can be a pain even though they are ghosted. Perhaps a timer that would retire those disconnected drivers after 5 or 10 minutes which should be ample time for people to try and rejoin.
While I like the more options on the MFD if they could be made more button box friendly that would be awesome perhaps a shortcut key menu.
F1 2016 was great in my opinion and really looking forward to F12017
