For example in Nashville, they have been trying to roll out fiber in Nashville for over a year now but have only been able to install on less than a dozen utility poles so far.
This is because of the rules that prevented anyone other than the owner of the existing lines to move anything. This meant that if Google wanted to add lines to a pole with existing AT&T and Comcast lines, it would require both companies to move their own lines independently of each other in coordination. This means roads would have to be closed 3 separate times for each vendor. Nashville recently passed the One Touch Make Ready ordinance that allows approved vendors to do all of the work at the same time.
Now both AT&T and Comcast are suing the city: http://arstechnica.com/tech-policy/2016/10/comcast-sues-nash...
I hope that google stills continues to deploy to cities that are already in progress. It took community effort to get the ordinance passed and subjects them a lawsuit. It would be a real letdown.
