Why did you suppose tom decides to let Wilson finally have the car he has been promising him the great Gatsby?

In "The Great Gatsby," Tom Buchanan decides to let George Wilson have the car he has been promising him as a way to distance himself from the consequences of Myrtle's death, which he indirectly caused. By giving Wilson the car, Tom attempts to project an image of generosity while simultaneously shifting the blame and avoiding any responsibility. This act also highlights Tom's manipulative nature, as he seeks to maintain his own comfort and status while disregarding the emotional turmoil of others. Ultimately, it reflects his self-serving attitude and moral indifference.
