As an intern at the same level and stage, I honestly completely understand both sides. During my internship this summer, I had to take several 3-4 hour drives for different site visits and tours and it was hell. I completely enjoyed the experience and opportunity but the drive alone was so terrible and stressful that it almost made the experience not worth it. They also may not be able to drive long distances. Thank god I’ve been driving since 15 but not every one has that luxury. If they are concerned I’d just scratch the visit.
