Apple Maps straight line distance
how do I stop my Apple Maps from giving me initially the straight line distance as opposed to driving distance? It’s quite frustrating. Say I am searching for a family member that is through find my iPhone. It says her initial distance in Dallas is 800 something miles but then when you click on it, it gives the driving distance of over 1000 miles. Clearly I am not flying across the sky to get there. Why does it do this? And can I change it?
