Maybe get unvolved in Student council or however they are called in you Uni and try to find some like minded people to change that or do some guerilla gardening, tactical urbanism etc. to get people to notice how stupid that is, i mean younger peope are usually way more open to less car dependency than the general population
I actually just graduated. I led a student advocacy group fighting for bike lanes and related things like getting rid of parking lots near the center of campus. I met with the student government dozens of times in my last year and had to explain to people almost every time how much of a waste of space parking is.
Its when you plant something somewhere without having the right todo so for example in order to protest.
So here they could put some plants on parts of the parking lots to fence an area off where he puts for example some benches, where people can study or something instead of cars parking there
