Commenting on Drivers and Staff...

Maybe its me, but I can't think of any reason why you wouldn't compliment your driver/staff using the 'Comment on...' feature.

Giving positive comments must surely increase moral and boost confidence in the team.

Perhaps demeaning your staff is good for giving them a kick up the backside? 

I think this is an area of the game that is to be expanded upon in the future but not at the moment.
I too don't see the point in saying anything bad - it doesn't help you but might help a competitor, so why would you do it?!?

It increases the relshionship with the person / sponsor it means for sponsors you could get a bit more money if you have a better relshionship with that sponsor

I do sometimes vent my frustration on rival drivers.



Nah not really, but still, I don't comment positive on my drivers unless I think they are good, but then again, I wouldn't have hired them if they weren't.
