Common Mistakes to Avoid

1. Ignoring transportation mode – Walking distance ≠ driving distance. A 1-mile walk might be 1.2 miles by car due to road networks.
2. Not accounting for traffic – The shortest distance isn’t always the fastest route during peak hours.
3. Overlooking elevation – Mountainous routes may show shorter “as the crow flies” distances but be much longer in practice.
4. Using straight-line distance – Always use the route distance, not the direct “as the crow flies” measurement.
5. Forgetting to update maps – New roads and closures can significantly affect distance calculations.
6. Not considering vehicle restrictions – Some routes may be shorter but inaccessible to large vehicles.

Advanced Tips for Power Users

• Use waypoints – Add multiple stops to calculate complex routes with up to 10 destinations
• Save frequent routes – Bookmark common trips in “Your places” for quick access
• Compare historical traffic – View traffic patterns by day/time to plan optimal travel times
• Export route data – Use the “Share” function to send route details via email or messaging
• Voice commands – Use “OK Google” to get distance information hands-free while driving
• Street View preview – Virtually “drive” your route to spot potential issues before you go
