How steep is that crazy hill by your house? Are they steep enough to ski if covered by snow? Hills look a lot different from a car than they do from foot or on skis.
It turns out that roads aren’t very steep at all. A good ski run is 15-25 degrees of slope with the craziest runs being up near 40 degrees. The steepest you’ll get on most roads is 5 degrees and that is certainly accompanied by warning signs. Most hills on the highway are barely 1 degree.
I know this thanks to a fun display on my new truck. It shows the pitch and roll of the truck as well as the how much the front wheels are turned. I suppose this might be important in certain off road situations, but mostly it’s just something fun to look at.
