Do you have a source for this? It doesn't seem to make any sense because the speed sensor is normally used as an input for the engine and brake control systems.

Do you have a source for this? It doesn't seem to make any sense because the speed sensor is normally used as an input for the engine and brake control systems. Not to mention the fact that the sensor is already extremely light because it's just a rotary encoder. GPS is also wildly inaccurate for speed measurement at low speeds and near tall buildings. I can certainly see using it in addition to a normal speed sensor for better accuracy at speed but as a replacement for weight savings it seems very unwise.
