What's the point of washing / cleaning up your car ?
It's all in our heads guys
EDIT #1:
Structural rigidity is a nice feature, but for me i see it as a reassurance/peace of mind for the most maniac of us (in trying to keep our car in shape)?
It would be the same thing as asking the little girl playing Barbie, "what's the point of buying your Barbie a Doll House?"
Just accept it

and return playing Barbie, hum, i meant Man Furismo 5
EDIT #2: someone ought to test out this feature:
- go take one of your cars,
- drive it around a track,
- destroy it as much as you can,
- leave the practice session/race
- take the same car to another track
- observed whether the behavior of the car is any different or still being affected by the damages you incurred to it in the previous race
- IF so, take the same car to have its rigidity fixed.
- Take the same car, (assuming rigidity has been fixed), to yet another track
- observe whether the behavior has improved or not...
Could someone please confirm?
