I think it’s a good idea, and I don’t think it would be expensive to implement. I assume it’s just some cameras and smart software to detect cyclists, and judge speed and trajectory. I suppose poor lighting could throw off the system. Infrared lighting could help. But you have to wonder what huge infra-red beams would be doing to other vehicles equiped with similar technologies like dash cams & automatic parking.
