How straight or bendy are the roads?

Using OpenStreetMap (OSM) data, I was able to see how bendy or straight the roads are all over the world. One theory I had was that Europe, where current roads are based on older roads that predate cars, would have more bends and curves than the USA, where current roads were (in many places) only put in in the last 150 → 100 years, and probably put in directly and dead straight.
