Does he not have a friend with a car? Either to borrow, or to get a ride from? No family?
Guess I’m lucky. With a few days’ notice, I have friends (and even neighbors I hardly know) who’d get a ride to their work with a coworker, and I could borrow their car.
I’ve also hitchhiked pretty long distances. But not being sure of getting there at a specific time would be stressful. Also requires looking friendly and harmless…
Is he a defendant? In which case, he’d have to arrive looking crisp and clean. But if he’s a juror… well, If that were me, I wouldn’t hesitate to bike to the bus. But I’d be sweaty til I washed up in the courtroom men’s room… okay, not a trick anyone else would pull, never mind.
ETA: In the age of Covid, I’m sure there are many people who are loath to walk into a building for a long period of time. He could even get a doctor to back him up, and say he needs to do this remotely… but I bet he could just ask and get help that way.
