This divider looks rather unforgiving. Is it common for dividers in US to be just plain concrete blocks without anything to prevent rapid deceleration?

- voxadam 9y agoIf you look at the imgur link you'll see a impact barrier that had previously been crushed and not reset or repaired.
- yani 9y agoI dont see it
- tstrimple 9y agoIt's in the techcrunch image, not the imgur. The barrier with the yellow face is designed to collapse. https://techcrunch.com/wp-content/uploads/2018/03/screen-shot-2018-03-27-at-7-51-49-pm.png https://techcrunch.com/wp-content/uploads/2018/03/screen-sho...
- newman8r 9y agothat image also makes me wonder if tesla's system is designed to identify knocked-over cones. It's one of those things that would be easy to code for, but also easy to overlook.
- xiphias 9y agoIt's quite hard if you take into account that machine learning needs 10000x the training data that a human needs, and Tesla is sold in 30+ countries (and used in much more). I think 3d mapping the surrounding world correctly using multiple cameras (what humans are doing) is more generalizable.
- arethuza 9y agoThat still looks pretty risky to me - I compared a similar junction here in the UK near to where I live (on the M90 in Fife) and it has about 40 impact attenuation barrels in a triangle.
- sgc 9y agoThose are also present in many locations in the US, although they seem to be phasing them out so I think they are considered old tech. I don't know the performance specs, but new cars are a lot smaller and safer than old cars - the same is probably true here too.
