I bet that such thing would happen if Real Damage on every Sport Race was implemented. and. the Damages would remain after the race... And to repair those damages, there would be the need to such repair being paid, with a corresponding value to the true amount of damages... like a car with 30% damage, to be "rescued" back to original, the price for the owner to pay would be at least 30% of the original value.. plus a fixed amount.. (that is only an example!

.
Of course that this only would be acceptable if in case of any damage inflicted to other cars, (the system needed to keep track of all damages inflicted to others, by fault from the driver), the cost from repairing the cars from other drivers to whom the driver was considered guilty of inflicting damage, would be automatically deducted to his accounts... and those other drivers would not have to pay a cent for getting their cars repaired...
If such system could ever be put to work.. I bet that the driving attitude would change immediately, from night to day...
Just consider the cost to pay for repairing a 20 million damaged car... such value deducted could bring to huge negative values for the racer.. and that would mean that he would need to race for a long time, with the other not damage cars until he could turn pay what he was "owing" to the "system" ... to be able to buy or repair his own cars...
I know this is UTOPIC.. to say the least... but some times Utopic ideas help to indulge into actions that may improve our .. reality.. just a little bit more...
