Not so great for cars

In Sapporo we get a lot of snow. The bigger streets are cleaned quite efficiently, but many smaller streets just have the snow compressed by cars running over it over and over again. The cars lose traction and the wheels spin, making ridges and ice. Man holes are slightly warmer, and melt the ice on top creating deep holes, etc. This makes these roads bad for cars. You can hear the cars lose half the underside or so when scraping against ice ridges...

This hole is near my house, though there are ones that are much deeper than this one. This photo was taken after a few warm days when much of the ice melted, making the hole more shallow too.
