By waste of land, I mean the place was built using several times more land than was needed for the relatively low population, but some clever fool with government money decide they'd build a bunch of small ghettos separated by large roundabouts.

My local town is in the process of sticking 'roundabouts' everywhere. Mayor visited someplace and liked them; he's pushing them on us now. Sometimes its just a dumb island in the middle of an intersection; you have to crank around it at microscopic speed which benefits no one.

The worst one has two lanes halfway around; one lane the rest of the way. From the south you can take the right lane and exit north without turning (much). But nobody understands the point; everybody stops and creeps around. So they put up a map(!) so you can figure it out. And 13 arrows and warning signs. All in the interest of 'efficiency'
