1. A computer having a processor and a memory, the memory storing instructions executable by the processor to:
access sensor data of a radar sensor of a vehicle while an adaptive cruise control feature of the vehicle is active;
detect, based on the sensor data, an object located along a path of travel of the vehicle;
determine that the object is a moveable object based on a radar return of a radar reflector of the object; and
responsive to the determination that the object is the moveable object, adjust, by the adaptive cruise control feature, the speed of the vehicle;
wherein the radar reflector is configured to rotate when the object is stopped or moving below a threshold speed, and wherein determining that the object is a moveable object includes detecting rotation of the radar reflector based on the radar return and determining a rate of rotation of the radar reflector, where different rates of rotation indicate different states of the moveable object.
