1. A method, comprising:
- obtaining, using one or more sensors, first sensor data regarding an environment of a vehicle and second sensor data regarding the environment of the vehicle, wherein the one or more sensors are operationally associated with the vehicle, wherein the vehicle is configured to operate in an autonomous mode, wherein the first sensor data is data regarding an aspect of the environment of the vehicle, and wherein the second sensor data is data regarding one or more other aspects of the environment of the vehicle;
making a determination whether the first sensor data and the second sensor data agree regarding the aspect of the environment of the vehicle, wherein making the determination whether the first sensor data and the second sensor data agree regarding the aspect of the environment of the vehicle, comprises inferring the aspect of the environment of the vehicle based on the second sensor data and determining whether the first sensor data regarding the aspect of the environment of the vehicle agrees with the inferred aspect of the environment of the vehicle; and
controlling the vehicle in the autonomous mode based on the determination.

Abstract
A vehicle configured to operate in an autonomous mode can obtain sensor data from one or more sensors observing one or more aspects of an environment of the vehicle. At least one aspect of the environment of the vehicle that is not observed by the one or more sensors could be inferred based on the sensor data. The vehicle could be controlled in the autonomous mode based on the at least one inferred aspect of the environment of the vehicle.
