This sounds nice, but is not the practice. Most states have laws that your guns must be disassembled during transportation. In Massachusetts, they will jail you if you even think about having a gun in your car. (Slight hyperbole there, but check out the laws in that ACLU-run state.)
Most universities ban all guns. That is quite diferent from the way things were in my youth, when my high school had a rifle team, and the members carried their rifles to school on the bus on days when they had meets. The bus driver would wish them good luck in the competitions as they borded. It was a different world then and in most ways a better one.

Actually, very few states have that as a requirement. Mostly the "extreme blue" states in the Northeast.
Massachusetts has become a disgrace to its own history. I'm sure John and Sam Adams are generating high wattage spinning in their graves.
