1. A computing system for generating a response of a vehicle to a virtual rumble strip, the computing system comprising:
a processor; and
memory communicably coupled to the processor that stores instructions that, when executed by the processor, cause the processor to:
determine that the vehicle has crossed a virtual boundary corresponding to a real-world location in proximity to the vehicle based upon first sensor data generated by the vehicle;
determine information about an environment of the vehicle as the vehicle crosses the virtual boundary based upon second sensor data generated by the vehicle;
prior to determine that the vehicle has crossed the virtual boundary, determine the real-world location corresponding to the virtual boundary based upon third sensor data generated by the vehicle;
establish the virtual boundary based upon the real-world location; and
activate an actuator of a seat of an operator of the vehicle such that haptic feedback is delivered to the seat, wherein the haptic feedback is based upon the information about the environment of the vehicle, a speed of the vehicle, an orientation of the vehicle with respect to the virtual boundary, and a type of the virtual rumble strip, wherein an active damping system of the vehicle prevents a passenger seat of the vehicle from undergoing the haptic feedback.
