Accepted a job with a brutal, unsafe commute - is it terrible and unprofessional of me to work there for a month or two and then leave?

I recently accepted a contract position at a charter school. I don’t drive, so I went to check out the commute in advance, and it turned out to be way worse than I expected. I am learning how to drive now, but the route to this school involves highways and narrow streets in the city. The school is in the part of the city that felt genuinely unsafe to me walking from the school. I was approached by multiple individuals, yelled at and followed. A local acquaintance also told me to avoid the subway and the train in that area.

On top of that, the commute itself is about 1.5 or 2 hours one way with no parking at the school. Because of my hours I need to leave super early like 5:30 AM which means walking in the dark in unsafe neighborhoods, especially once it’s winter.

The job starts in about two weeks. I’m seriously considering whether I can do this long-term, but I also don’t want to back out before I even start, especially since I love the school’s philosophy and principles. I’m thinking about giving it an honest try for a month or two and if it’s not workable, give notice with enough time for them to find a replacement, then look for something closer with actual parking or safer commute.

Would this be a bad move on my part? Has anyone else taken a job, realize the commute safety situation was unworkable and left after short time? How did you handle the transition or explain it to your employer? I appreciate any perspective trying to figure out if I’m overacting or if this is a legitimate reason to make a change.
