those cars were cool. i watched the video but it didn't understand why they stopped racing the Group B cars. i also couldn't understand what the guy said after the crash when he was reading some sort of statement from 2:00-2:35 or at the end when the screen went black becaus eit was in another language.
They stopped racing group B following a number of fatal accidents involving both drivers and spectators.
The final accident was when thirty-one people were injured and three were killed during an acciedent in the Rally of Portugal in '87. Joaquim Santos came over a rise to find the road blocked with spectators, he lost control of his RS200 while trying to stop and hit the crowd.
