I just noticed this feature in Google Maps that now in Nicaragua they have actual driving directions and there is even a 3-D option that flies you through the landscape so you see how hilly and/or curvy the roads are. In this example you go from Managua to Esteli.
To me this is a great assist for travelers looking to better plan their trips, especially if driving oneself.
Just a word of caution, I would add approximately an hour to any destination that Google’s driving time estimate is more than an hour. So if it says one hour plan on two, if two hours better make that three, etc.
Try the 3-D feature, I think you will enjoy it!
