1. Increasing the Friction: The speed at which a car can move around a roundabout is largely dependent on the friction between the car's tires and the road. If the friction is low, the car is more likely to skid or slide, which means it must go slower to maintain control. If the friction is increased, for example by using tires with better grip or improving the road surface, the car can go around the roundabout at a higher speed without losing control.

2. Lowering the Car's Center of Mass: The car's speed around the roundabout is also affected by its center of mass. A lower center of mass makes the car more stable and less likely to tip over, which allows it to go around the roundabout at a higher speed. This can be achieved by lowering the car's suspension or using a design that naturally has a lower center of mass.
