Bikes are mainly curved, small pieces of metal, and absorptive pieces of rubber. Their reflectors are designed for viewing them from the front or rear, not the sides. I wonder whether lidar can even differentiate a sideways bike from noise.
- taneq 9y agoEven if the bike itself was too spindly to be picked up, there's no excuse for missing the solid mass of a human body.
- philip1209 9y agoIn principle, I agree. But, I wonder if holding a bike in front of you is almost like holding a mirror that obscures the lidar ability to detect a solid mass. edit: but she is in front of the bike, so this shouldn't matter. Does the darkness of her clothing impact any of the sensors?
- stouset 9y agoTo hell with the LIDAR, human beings are practically IR flashlights. Aren’t these things supposed to have multiple sensors?
- stevenwoo 9y agoAll bikes sold in the United States are required to have reflectors on the wheels for reflection to the right and left. Enthusiasts often remove them.
- birken 9y agoEven if those in-wheel reflectors are removed, the wheel rims are reflective and the seat post is reflective (at minimum). And additionally there are several things that are way less reflective than a bicycle that you don't want to hit in the middle of the road. Like a deer, or a pothole, or a pedestrian. A bicycle shouldn't need to be covered in reflectors to be safe from getting run over by a car. However anybody who cycles at night (as I do frequently) should wear reflective clothing because the road is full of reckless drivers.
- dwighttk 9y agoI don't think this is true. I would be surprised if there were much federal regulation about bicycles.
- heartbreak 9y agoYou can see the side reflectors on the bicycle in this video.
