Yes and also it shows that typical 'offroad' reaction where the car usually bounces up and down in the grass illepall. Happens all the time when a car goes in the grass on rFactor... it is like some pre defined effect when the ground/grass is really just flat, so stupid.
Sorry to disappoint you, but LFS uses a pre defined offroad effect as well, some sort of micro bumps. But it's probably better done so you hardly notice it.
The one in LFS isn't like this though. EVERYTIME a car goes off the track in rFactor (or at least in the grass and sand), it makes a sort of washy effect like it is going up and down in the ocean... like a boat! It is so odd. LFS at least rides on the shape of the track. And yes, there is a rumble effect of grass or whatever, but that is different... the entire car isn't wobbling.
I always get a giggle when somebody says they used GPS data to accurately model something.
This is something I know more than a little about. GPS data can be mm level accurate, but it takes a lot of knowledge, time and effort. GPS positions can be plus or minus 30 meter accuracy too if you just use a standard receiver with no corrections.
You also have to stitch things together correctly and if you don't know what you are doing, then the results are not good.
So, just saying you have "GPS" data, does not mean that anything will necessarily be accurate.
