9. The system of claim 1 , wherein the one or more cabin components include an indication system of the vehicle; and

wherein the one or more computing devices are configured to:

alter the one or more cabin components of the vehicle before the acceleration time by providing a visual, audio, or haptic indication using the indication system; and

adjust the one or more cabin components of the vehicle based on the acceleration of the vehicle over time by adjusting the visual, audio, or haptic indication based on a rate of acceleration of the vehicle.

10. The system of claim 9 , wherein the indication system of the vehicle includes one or more lights; and

wherein the one or more computing devices are configured to provide the visual, audio, or haptic indication by increasing an amount of light from the one or more lights before the acceleration time.

11. The system of claim 9 , wherein the indication system of the vehicle includes one or more speakers; and

wherein the one or more computing devices are configured to provide the visual, audio, or haptic indication by emitting a sound from the one or more speakers before the acceleration time.

12. The system of claim 9 , wherein the one or more computing devices are configured to alter the one or more cabin components at least approximately 0.5 seconds before the acceleration time to compensate for a perception delay of a passenger.

13. The system of claim 1 , further comprising the vehicle.

14. A method for adjusting one or more cabin components of a vehicle, the method comprising:

determining, by one or more computing devices, (1) an acceleration of the vehicle in a first direction and (2) an acceleration time associated with the determined acceleration, the acceleration time being a future point in time where the determined acceleration is predicted to start, and the acceleration time being determined based on a position and trajectory of an object that intersects a route of the vehicle;

altering, by the one or more computing devices, the one or more cabin components of the vehicle before the acceleration time; and

adjusting, by the one or more computing devices, the one or more cabin components of the vehicle based on the acceleration of the vehicle over time.

15. The method of claim 14 , wherein determining the acceleration time includes determining a point in time where the acceleration of the vehicle exceeds a minimum threshold acceleration.

16. The method of claim 14 , wherein the one or more cabin components include a seat of the vehicle, the seat having a default position, and a gimbal configured to control the seat; and

wherein the method further includes:

altering the one or more cabin components of the vehicle before the acceleration time by tilting a top of the seat toward the first direction from the default position to a tilted position using the gimbal; and

adjusting the one or more cabin components of the vehicle based on the acceleration of the vehicle over time by moving the seat from the tilted position towards the default position using the gimbal.

17. The method of claim 14 , wherein the one or more cabin components include a seat of the vehicle and a vibration mechanism configured to vibrate the seat; and

wherein the method further includes:

altering the one or more cabin components of the vehicle before the acceleration time by vibrating the seat using the vibration mechanism; and

adjusting the one or more cabin components of the vehicle based on the acceleration of the vehicle over time by adjusting an intensity of the vibration over time based on a rate of acceleration of the vehicle.

18. The method of claim 14 , wherein the one or more cabin components include an indication system of the vehicle; and

wherein the method further comprises:

altering the one or more cabin components of the vehicle before the acceleration time by providing a visual, audio, or haptic indication using the indication system; and

adjusting the one or more cabin components of the vehicle based on the acceleration of the vehicle over time by adjusting the visual, audio, or haptic indication based on a rate of acceleration of the vehicle.
