1. A method, comprising:
comparing, by a first autonomous vehicle, first environmental information, representative of a physical environment and generated by a first sensor of the first autonomous vehicle, to second environmental information representative of the physical environment and generated by a second sensor of a second autonomous vehicle, wherein the second environmental information is concurrently generated with generation of the first environmental information; and
in response to determining, based on the comparing, that the first environmental information comprises a discrepancy with respect to the physical environment that is not represented in the second environmental information, activating, by the first autonomous vehicle, a secure sensor of the first autonomous vehicle to generate third environmental information representative of the physical environment to determine whether the discrepancy accurately describes the physical environment for navigating the first autonomous vehicle.
