1. A method comprising:

  • receiving from a speedometer of a vehicle having an autonomous driving mode, a first current speed of the vehicle;

    receiving, from a displacement measuring device, displacement information identifying a first orientation of a first rotor at a first time and a second orientation of the first rotor at a second time;

    determining, by one or more computing devices having one or more processors, a second current speed of the vehicle by determining a displacement value between the first orientation and the second orientation;

    determining, by the one or more computing devices, whether to continue using speeds determined by the speedometer to control the vehicle in the autonomous driving mode based on a difference between the first current speed and the second current speed; and

    controlling, by the one or more computing devices, the vehicle in the autonomous driving mode based on the determination of whether to continue using speeds determined by the speedometer.
