Lyft doesn't annotate vehicles on the opposite side of the road. See a quote from the supplementary material of the ST3D paper.

"The Lyft dataset does not annotate objects on both sides of the road. For instance, we observe that the objects on the main branch of the road (w.r.t the ego car) are most likely annotated, while many objects on both sides might not be annotated."
