Automotive companies choose to license their cars in racing games like Forza or Gran Turismo for several reasons, while being more hesitant about the Grand Theft Auto series:

1. *Positive Representation*: Racing games are primarily about the celebration of cars, driving, and motorsport. Cars are shown in a positive light, focusing on their performance, design, and history. This aligns well with the image that car manufacturers wish to project.

2. *Brand Image*: Grand Theft Auto, while immensely popular, has themes of crime, violence, and other mature content. Car manufacturers might be hesitant about associating their brands with such content.

3. *Damage and Misuse*: In the GTA series, vehicles can be stolen, damaged extensively, used in criminal activities, or even destroyed. Such depictions might be unappealing to car manufacturers who want to maintain a certain prestige or image for their vehicles.

4. *Target Audience*: Racing games appeal to car enthusiasts and people interested in the automotive world, making them a fitting platform for car manufacturers to showcase their vehicles.

5. *Historical Precedence*: Racing games have a long history of featuring licensed cars, dating back many years. This has established a tradition and trust between game developers and car manufacturers.

6. *Feedback from Fans*: Fans of racing games often expect and appreciate the realism that comes with using licensed cars, whereas the GTA audience might not prioritize this as much.

While the potential exposure in a game like GTA might be vast, automotive companies must weigh the benefits against the possible damage to their brand image.
