1. A method for predicting turning and braking actions of vehicles, comprising:
at a first vehicle including one or more processors and memory:
obtaining a plurality of images along a road;
for each image of the plurality of images:
detecting, from the image, a plurality of image regions each corresponding to a respective vehicle light of a second vehicle positioned on the road near the first vehicle;
normalizing an intensity of the respective image or image regions;
generating a composite image that includes the plurality of image regions, each image region of the plurality of image regions corresponding to a respective vehicle light of the second vehicle; and
determining, for each image region, a probability that a respective vehicle light of the second vehicle changed its state;
predicting a vehicle action of the second vehicle based on the probability for each image region; and
at least partially autonomously driving the first vehicle based on the predicted vehicle action of the second vehicle.
