A bit of backstory... My little cluster of townhomes sits beside a 35mph, wide (was 4 lanes, reduced to 2+bike lanes), busy suburban road. Cars regularly go 50mph because the road is wide and smooth and 50 feels right. People have died crossing the road (2 in the 7 years I've lived here). There's a bus stop on both sides of the intersection, housing on both sides, a park on one side down a block, and a golf course on the other side, also one block down.
The response from VDOT was essentially "there's currently no proof of pedestrian need" This despite bus stops, parks, and housing existing. And pedestrian deaths. And frequently seeing with my own eyes people dashing across the road, trying not to get squished,
It's complete idiocy from the various traffic planning orgs. It's 100% car-first, consequences be damned. Bike lanes are added reluctantly, and usually as a requirement to get federal funding; little attention paid to utility... did I mention the bike lanes on the road above go "nowhere"? They literally end several blocks on either side of the local school complex, start again, then stop before the local shopping center. So you can't actually use them to get anywhere you'd want to go.
Well of course. Just how there's no proof of "train need" before tacks get built. Why do we ever build tracks if there is no preexisting train traffic to justify the need?!
The college students also generally don’t vote in that location lowering the desire of public government to engage with them as much. Again transient. You’re right to ask but I’m guessing this was the primary issue.
* We don't have "college students". We have however real students, e.g. in University.
* Over here it's not custom to go with micro-management problems to an elected person, e.g. to the member of parliament of your area. Whenever I see the (partially propaganda) shows where russians ask the dictator Putin about day-to-day things and they even air this yearly in the TV I cringe. Or when I see in US movies that people go with low things to their congressman... that simple isn't custom in Germany. And thus the elected people are much LESS likely looking if people wanting something would elect them or not.
* Normally it is the executive, not the legislative, that decides over these matters. In Germany, the executive isn't elected by the public.
* In Germany we have the idea of "main point of living" (Hauptwohnsitz) and "secondary point of living" (Zweitwohnsitz). And in quite a few towns you have to pay an extra-tax on the Zweitwohnsitz. There are ways to mitigate this, but the easiest solution as a student is just to take your Hauptwohnsitz at your university town. And there you can then vote (you can't vote at your Zweitwohnsitz). And so it happens that the town magistrates of student towns are usually a bit different than of "normal" towns, e.g. the town mayors from the green party. All these young students voting more for this party than e.g. the german liberals.
So, all in all, from the POV of the story in Berlin ... little of what you wrote made sense. Except your first sentence. Infrastructure building is a slow, a tremendously slow process in Germany (however, once we have it, it's usual very nice. We germans call shit on our railway ... but it's lightyears better than e.g. the US railways system!). And even a zebra crossing falls under the infrastructure categorization.
Doesn't make for a good story though. What I relayed above has become university lore. Its accuracy is hard to judge decades later.
