I get where you're coming from but you could say the same about circuits in racing games including Le Mans then and two people were sadly killed on the Nordschleife just last month.Honestly im surprised that Group B rally cars are featured in racing games.
Group B despite being the golden days of rally was also dark with the numerous fatalities.
Due to the numerous fatalities you would perhaps see some resistance in putting these cars.
Then again Motorsport will always be a dangerous sport no matter what. Its much more safer today due to technology along with rules and regulations. But still death can happen at any moment in the sport.
