Ex-Apple Engineers Build a Speed-Spotting Lidar for Self-Driving Cars

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.
