> slow down cars in urban areas This is actually happening. Portland has recently fallen in line with other cities, like Seattle, and lowered thousands of miles of streets from 25 MPH to 20 MPH. http://www.oregonlive.com/commuting/index.ssf/2018/01/portland_poised_to_drop_speed.html http://www.oregonlive.com/commuting/index.ssf/2018/01/portla...

In the UK a lot of residential areas have introduced 20mph limits (down from 30mph), close to no-one (except learner drivers) obey this new limit! :(

  It's still an improvement, since before they didn't obey the 30mph limit. 25mph is much better than 35mph.
  - richrichardsson 9y ago
    My experience/estimation is it's still > 30mph they are driving. :(

  Automated speeding tickets will fix that quickly

    Indeed. And automated driving will end a great deal of greed based revenue as well. And given the sensor data, proving lack of violation is trivial. The $64k question is: what will states and counties do without police citation revenue?
    - intrasight 9y ago
      Automated enforcement revenue will be much higher
      - crankylinuxuser 9y ago
        Indeed, but when the automated system driving verifies real-time what the limits of the road are, it is trivial for an "Auto" to dispute and provide evidence. The only thing these auto-scammers would get are human drivers not driving precisely and accurately.

  Generally it only takes one driver wanting to stick to the limit for everyone else to do so too, because overtaking is contraindicated. Which isn't to say that it never happens :(. I live in Edinburgh, which has been gradually introducing 20mph limits over the last couple of years, and I've actually taken to them much better than I'd expected to: they don't reduce my average speed all that much, especially as the arterial roads are still 30mph, and they're much more pleasant when I'm out of the car.

Portland is also re-purposing in town red light cameras to issue speeding tickets. http://www.kgw.com/news/local/red-light-cameras-can-catch-you-speeding-starting-thursday/480208579 http://www.kgw.com/news/local/red-light-cameras-can-catch-yo...

  If they actually start issuing tens of thousands of speeding tickets as a result, someone is going to successfully use Oregon's initiative system to ban those cameras altogether.

That's interesting, because Cambridge, MA made a big deal about lowering the limit to 25 MPH in 2016 - which is still way too fast for most neighborhoods. I'd much rather see it taken down to 20 and even 15 for side streets. The funny thing though is, I haven't noticed one iota of difference in the speed that cars are actually traveling.
