I think it would be great if when preparing for a driver swap the passenger (incoming driver) had acces to the pit menu of the car he was taking over so he could select fuel levels tyres etc. This would save the outgoing driver from having his attention taken up with setting the menu for the incoming driver and leave him free to concentrate on racing.
yes, sounds good. but some system to limit an access to those data must be developed. for example no one want to share own tyre/fuel strategy with drivers outside own team
