It’s lunchtime, and the worker bees of Mountain View who aren’t interested in their company’s own catering are walking down East Middlefield Road in search of grub. It’s a lovely esplanade, but all the trees and light poles make these pedestrians hard to spot.

That makes things tricky for a human driver, and extra troublesome for a robot trying to learn to work the wheel. But on a large monitor inside Soroush Salehian and Mina Rezk’s Mercedes Sprinter van, every meandering biped stands out against a sea of white. Those walking toward the van are blue, those moving away from it are red.

The readout comes from the lidar laser sensor sitting in a box on the vehicle’s roof. Salehian and Rezk, cofounders of a startup called Aeva, have built one of the few sensors for self-driving cars that can see not just where things are, but how fast they’re moving. Moreover, inside that rooftop box is not just the lidar, but a camera and a radar, whose diverse data streams Aeva compiles into a single image, correlated down to the pixel and the nanosecond.
