New report highlights limitations of Cruise self-driving cars

For example, we have loops in our ROS node graph. Any student can tell you that the variance of the sum of two independent gaussians is the sum of the two variances. What this means is, variation in delay accumulates and the scheduling of the system is unstable.

There are people problems too. For example, the head of perception is a pathological liar. Another example: one of our founders jokes in private (when he's drunk, as he often is) that he's a "fraudster" and everyone knows there's a grain of truth there.
