When you went into the grass at 1:13 I didn't see any extra understeer that you'd expect to see when steering and going from a high-grip track surface to a low-grip grass surface.
When you righted yourself and then accelerated ON THE GRASS the acceleration looked the same as the acceleration after the previous corner at 1:09 when you were ON THE TRACK...
That video makes it appear there is no loss of grip on the grass...
Besides, that 180 spin before turn 1 just looked like an arcade game... (that the tires have too much grip, as appeared before from the grass example, so when the tires were pointing in the direction the car was going, it gripped and was now going perfectly backwards... Possible, but just how often have you seen F1 drivers do these perfect 180s and then be going backwards?)
I don't think the physics have to be funny for this to happen, just that the grip level of the tires is ridiculously high...
Undoubtedly the PS3 has the power for a good sim, so maybe I was expecting too much out of a $600 box...
(GT3/4 didn't seem to have the issues I saw in this video...)
