Computers giving cyclists a "right hook" sooner than expected
Of course we all know that computers are going to take over the world and make people their slaves, but perhaps it's happening faster than we thought:
https://techcrunch.com/2016/12/20/ub...ars-bike-risk/ Jay, would you please file a few big-dollar wrongful death/personal injury lawsuits against the self-driving car companies and put them out of business? Thanks. |

Sorry, I didn't notice that Frank had already started a thread about this. I defer to his thread.

"Better living through technology" I wonder how well those things work. They're said to use thermal imaging, IOW infra red, I suppose. But ISTM that at certain ambient tempreratures there might not be much temperature difference between the bulk of a cyclist's image and the surrounding road. That would depend on choice of outerwear. A jacket over a sweater, for example, might be the same temperature as the air, especially in front where it's being cooled by the relative wind. Helmets would certainly be at ambient temperature on their outside. Cyclists with rain capes or with front loads might have their legs hidden from such a camera. Our porch has a light controlled by a motion detector, but it too seems to be IR based. There are times it refuses to respond. I assume that's due to lack of temperature contrast. -- - Frank Krygowski |

There is a HUGE difference between Therma Imaging and Infra Red. Infra red imaging is greatly reduced by things such as rain, fog and/or smokke whereas Thermal imaginging will still work very well in those conditions. That's why the military prefers thermal imaging to infra red imagin on scopes etcetera. Thermal imaging can pick out troops lying in the snow or even underthe snow. Again, infra red and thermal imaging are two very different things. Cheers |
