Systems and methods of the present disclosure include a motion planning module that iteratively determines possible trajectories for a vehicle to follow, calculates an estimated cost associated with each possible trajectory based on cost functions and cost weights, each cost function corresponding to a trajectory evaluation feature, and selects an optimal trajectory having a least associated estimated cost. When the vehicle is operated in a learning mode, a learning module determines a first actual trajectory traveled by the vehicle, compares the first actual trajectory with the optimal trajectory for that time period, and updates the cost weights based on the comparison. When the vehicle is operated in a teaching mode, a teaching module determines a second actual trajectory traveled by the vehicle, compares the second actual trajectory with the optimal trajectory selected for that time period, and generates output to a user of the vehicle based on the comparison.
