I'm sure Google didn't put any thought into their physical rollout.

From the article:

“If anyone understood road technology or tire technology, [they] would know it’s going to be a problem,” said Jim Hayes, president of the Fiber Optics Association and a decades-long veteran of the industry.

“They bid out the work to replace the sealant with asphalt,” Simrall said. But before the work started, Google Fiber saw customers lose service when the process of repaving roads damaged fiber lines. “So they shifted their attention to addressing that,” she said.

Apparently, they did not in fact put any thought into it, besides "how can we cut costs".
