Real roads follow parallel paths (like wheel tracks) that maintain consistent curvature. Circular arcs preserve parallelism perfectly and offer simpler intersection calculations than Bezier curves. For high-speed infrastructure, clothoids (transition curves) provide smooth curvature changes, though they're mathematically complex. The author is building a custom road system for city builders using circular arcs as a more realistic alternative to standard Bezier-based approaches. ## Full article daily.dev links to this article rather than hosting it.
