    Might also make pedestrians a bit more careful.

    An autonomous car that isn't in beta (death) testing phase should be far safer than a human driver. LIDAR can be used to see around corners and the computer can react to circumstances in milliseconds rather than hundreds of milliseconds. So I don't see it having an effect on pedestrian behavior. In fact, if pedestrians know that autonomous cars will always halt when a pedestrian gets in the way, they may be motivated to jaywalk more.

    We always knew that people would die from autonomous cars. "Zero fatalities" isn't realistic.

    How does lidar see around corners? Bendy light?

      Stanford Researchers Develop Non-Line-of-Sight LIDAR Imaging Procedure [soylentnews.org]

      NLOS [(Non Line Of Sight)] imaging reconstructs the shape and albedo of hidden objects from multiply scattered light. Despite recent advances, NLOS imaging has remained impractical owing to the prohibitive memory and processing requirements of existing reconstruction algorithms, and the extremely weak signal of multiply scattered light. Here we show that a confocal scanning procedure can address these challenges by facilitating the derivation of the light-cone transform to solve the NLOS reconstruction problem. This method requires much smaller computational and memory resources than previous reconstruction methods do and images hidden objects at unprecedented resolution. Confocal scanning also provides a sizeable increase in signal and range when imaging retroreflective objects.

    I don't think that "lidar seeing around corners" is realistic outside of a controlled environment. It's one thing for "over the horizon radar" to work, as the sky is a pretty uniform environment, it's another for lidar to see around corners. Yes, they've done it in a controlled environment, but that's not a typical use case.
