Vehicle.GetRandomDriver() Creating Same Ped Model

So I'm running into an issue with one of my callouts where I need to create a random driver for three different vehicles at different times during the callout. My code for each instance is as follows:

 Driver1Sent = true;
                    SpeedVehicle1 = new Vehicle(Tools.Tools.RandomCarModel(), SpeedSpawn);
                    SpeedVehicle1.IsPersistent = true;
                    Driver1 = SpeedVehicle1.CreateRandomDriver();
                    Driver1.IsPersistent = true;
                    Driver1.BlockPermanentEvents = true;

 Driver2Sent = true;
                    SpeedVehicle2 = new Vehicle(Tools.Tools.RandomCarModel(), SpeedSpawn);
                    SpeedVehicle2.IsPersistent = true;
                    Driver2 = SpeedVehicle2.CreateRandomDriver();
                    Driver2.IsPersistent = true;
                    Driver2.BlockPermanentEvents = true;

 Driver3Sent = true;
                    SpeedVehicle3 = new Vehicle(Tools.Tools.RandomCarModel(), SpeedSpawn);
                    SpeedVehicle3.IsPersistent = true;
                    Driver3 = SpeedVehicle3.CreateRandomDriver();
                    Driver3.IsPersistent = true;
                    Driver3.BlockPermanentEvents = true;

The issue I'm running into is that the driver of each car is always the exact same model every single time. Is there something obvious that I'm missing here? Any help will be appreciated 🙂
