I think you are reading a LOT into the fact that these pictures have just surfaced. It seems there are a few investors involved and the money required to run an F1 team is significant. Therefore those who are providing the money will be diligent enough to ensure Lotus are doing at least the obvious to be competitive.
I disagree, the people involved in the Lotus team won't be going into their first season thinking it will be for learning purposes. Imagine going to your investors and saying... "don't expect anything from us from the first year, we'll still be developing the car..." That sort of attitude would've never let Brawn get on the grid in the first place.
I think every realistic privateer team will know they will be playing catchup, probably spend months just smoothing out the operation, that's always the case with privateer teams in F1. Probably 1 out of 6 will have some success and survive in the sport, that's just how it is.
I have driven two protons and i have to say they are absolutely rubbish. The engine is seriously underpower, the ride is rubbish, the interior is rubbish (and has wayy too much plastic), the brakes are rubbish, its too noisy in the cabin, not enough room........
