Can confirm for my kid at Kenyon as well. All housing is within walking distance of the dining hall and classrooms so most of the time, the cars just sit there. There are students with cars (every friend usually has one) and regular shuttles to Mt. Vernon. When the weather is good, there is a bike path that goes from campus to Mt. Vernon (that’s 6 miles one way though). There is also Instacart and DoorDash, on-campus delivery from the Mt. Vernon pharmacy for prescriptions, and obviously mail order for anything else.
Here’s the bike path: http://www.kokosinggaptrail.org/
I would suss out housing for campuses. It’s probably pretty walkable/bikeable if there is a lot of on-campus housing. A lot of students from the suburbs/rural areas already have cars, which I think is why there are so prevalent on campuses. My nephew brought his to college (not Kenyon), because his housing is far away and the weather and the route were not always conducive to biking.
