1. A vehicle comprising:
a suspension assembly associated with a wheel;
a first feature;
a first camera; and
a processor to execute instructions to:
capture, via the first camera, a first image including the first feature and a second feature, the first feature and the second feature having a first spatial relationship in the first image;
capture, via the first camera, a second image including the first feature and the second feature, the first feature and the second feature having a second spatial relationship in the second image; and
determine, based on a difference between the first spatial relationship and the second spatial relationship, a deflection of the suspension assembly; and
modify a performance characteristic of the vehicle based on the deflection.
