1. A method of operating an autonomous vehicle, comprising:
determining, by a computer located in the autonomous vehicle, a trajectory related information of a vehicle operating on a roadway on which the autonomous vehicle is operating, wherein the trajectory related information for the vehicle includes a speed of the vehicle and a set of points on which the vehicle is predicted to travel;
receiving, from a sensor located on the autonomous vehicle, sensor data of a first area that includes the vehicle;
determining an additional trajectory related information for the autonomous vehicle by comparing the trajectory related information of the vehicle to a current trajectory related information of the autonomous vehicle,
wherein the additional trajectory related information is based on a category to which the vehicle belongs that is determined using the sensor data, and
wherein the additional trajectory related information allows the autonomous vehicle to maintain at least a distance between the autonomous vehicle and the vehicle; and
causing the autonomous vehicle to operate in accordance with the additional trajectory related information of the autonomous vehicle,
wherein, in accordance with determining that the trajectory related information for the vehicle indicates that a number of lane crossings performed by the vehicle over a lane boundary of the roadway is greater than a number within a predetermined amount of time, the additional trajectory related information for the autonomous vehicle is configured to increase the distance between the autonomous vehicle and the vehicle.
