I'd be willing to bet that more public transport options will be added in expansions, that's seemed to work well for them in the Sims. I'd love to lay highway too, but it looks pre-built in the video. Not really concerned about a lack of power lines and pipes, I eventually modded that bit out of SimCity 4 (it's just not fun).
Always. Seriously though, being the first 3D SimCity (and the first with curvy roads) means there’s some serious spline tech under the hood. We’ve got a few old, grizzled engineers (including some from the SimCity 4 days) making sure your splines are reticulated to perfection.”
