Systems and methods generate an account recovery key for a protected system. The process comprises feeding a solution comprising a solvent and diphenyl oxide andor partially brominated diphenyl oxide into a reaction zone containing a refluxing reaction mixture comprising an excess of bromine and a catalytic amount of Lewis acid bromination catalyst. This will cause the ECM, according to its normal engine management software, to derate the engine performance to a no air torque setting, thereby limiting the amount of torque that the vehicle operator can extract from the engine. Measures for redundant signal processing are taken, and data is transmitted in a fault-tolerant, redundant and bidirectional fashion. The image sensing system detects lane markers on a road being traveled by the vehicle and present in the field of view of the imaging sensor.
