What does that have to do with building? --- End quote --- Tell that to the Dutch government. >:D. In the Netherlands there is this whole ordeal about farmers and the emissions of "stikstof" which translates to nitrogen. Due to the fact that the emissions are to high nature is suffering, is the argument. The little of what is left of nature is having ill effects of all these emissions. Why the building trade is suffering of it is due to the fact that the process of building also brings all sorts of emissions. Think of the vehicles for deliveries, cranes to lift things, etc. But the controversial bit in the whole thing is that due to population growth and more and more people staying or becoming single there is the need for >100000 new homes build every year. :-DD P.S. the population growth is not due to birth, but due to the in stream of asylum seekers. |

I think the happy medium would be to have self driving corridors. Make all highways have the infrastructure in place. Once you hit a town then you have to take over for the side streets. The infrastructure could be as simple has having posts with transponders of sort on them or even just QR codes or other subtle markers that are easy to pickup by automation. Ideally it should be something passive that requires no power since there is no power along most highways, at least not low voltage. GPS on it's own is not accurate enough especially at driving speeds and required reaction times. Ex: driving 100km/h less that a foot away from other cars, civilian GPS is just not accurate enough to make that kind of judgement in real time like that. The issue with self driving as is right now is it relies on lot of things to be perfect, such as the road being very clean, no pot holes, no snow, proper lines and signage, etc. That is not a very typical road at all. Highway 11 for example is usually snow packed, and most roads are full of potholes that you need to avoid. |

I want to avoid the area. Afaik GPS is not used directly for guidance or navigation. The information is melded with rate and acceleration sensors and the radar sonar and vision sensors to get an estimate of where the car is. Much like human drivers do. And as prior posters said, because the details are different the successes and failures are different. |

For new town experiments I had countries with a little more room and a little less EU in mind. |
