1. A method of processing information regarding movement of a first vehicle based on information regarding movement of at least one second vehicle, the method comprising:
receiving, by a receiver supported on the first vehicle, a communication from a transmitter supported on the second vehicle, the received communication including a location of the second vehicle and information generated by an inertial measurement unit (IMU) of the second vehicle indicating movement of the second vehicle corresponding to temporary lateral or vertical acceleration of the second vehicle experienced by the second vehicle at the location, the temporary lateral or vertical acceleration being caused by an environmental condition encountered by the second vehicle at the location;
using a processor to process the information from the received communication and determine that the first vehicle is following the second vehicle while traveling on a road;
using information from an IMU of the first vehicle to identify a sensor indication of movement of the first vehicle indicating temporary lateral or vertical acceleration of the first vehicle experienced by the first vehicle at the location that corresponds to the temporary lateral or vertical acceleration experienced by the second vehicle at the location, the temporary lateral or vertical acceleration experienced by the first vehicle being caused by the first vehicle encountering the same environmental condition that affected the movement of the second vehicle at the location;
excluding the identified sensor indication of the movement of the first vehicle that corresponds to the temporary lateral or vertical acceleration experienced by the first vehicle at the location caused by the first vehicle encountering the same environmental condition that affected the movement of the second vehicle from information used by the processor to determine movement of the first vehicle;
determining movement of the first vehicle, using a dead reckoning technique, based on remaining non-excluded sensor information from the IMU of the first vehicle indicating movement of the first vehicle at the location that does not include the identified and excluded sensor indication of the movement of the first vehicle; and
controlling at least one system of the vehicle based on the determined movement of the first vehicle by providing driver assistance or autonomous vehicle control.
