Many externships my average was 70-80 minutes for commuting, with some places requiring as much as 2.5 hours for a commute.
I had only 1 externship where my drive was less than 30 minutes regularly.
Some days I wondered how I could be so tired, but then I remembered I had driven nearly 6 hours in a day on top of the surgery, clinic, academics, etc.
Driving fatigue is real.
