There are thousands of miles of sidewalks in NYC, 99.9% of them unprotected by bollards where someone can mow down crowds. There are 1000s of cafés and restaurants with their windows open on the street, where the same thing or a Bataclan scenario can happen. Why only subway entrances?

It's a brand new entrance. If youre already spending $177 million (yes, $177 million) on a new staircase an elevator, you can afford the two bollards needed to protect it.

Unnecessary requirements are how you get to a single station entrance costing $177m.

It’s not “only subway entrances”, it’s anything that NYC’s processes put in front of a community board. Routine DHS-mandated bollards installation in places like Times Square doesn’t go in front of them. Not saying it’s rational, but the post-9/11 trauma is palpable.

And post-bike path attack, but again, we’re not closing down every bike path because of terrorism.

Downtown NIMBYs used this idea to try and jam up some elevator projects on Broad St www.nytimes.com/2018/01/22/n...

On the one hand there's a non-material hypothetical increase in the chance of "terrorism" on the flip side the system will fulfill its legal and moral obligation to be accessible to those with disabilities. Who is to say which is better?

I’m sorry, who’s bombing the elevator with 3 people on it and not the train with 300 people on it 30 seconds down the time path? By this rationale, we should shut down the J too.

Which looks like it got nicked by it :/

Imagine Paris saying, "I think we should ban all al fresco dining and reftrofit all cafés with bullet-proof windows because it increases the opportunity for terrorists to run an attack" after Bataclan night.

Paris has thousands of not hundreds of thousands of sidewalk bollards

It's bollards to prevent parking on the sidewalk. They won't withstand a golf cart.

It has flimsy parking posts that would not stop a car at speed, meant to discourage illegal parking on the curb. It has *very* few crash-rated bollards.

Well, then there are govts that follow through and that way you get airline-like security for long-distance trains in Spain for example.

I’m sure you could find some spots where they’d try to use it to nuke the nightlife

I mean we have to do this with almost all large-ish festivals these days. Magdeburg had a concept to prevent a vehicular terror attack, it was just bad and wasn't fully implemented, with tragic consequences.

The local Carnival Parade were I live involved two seperate garbage trucks being parked on the main road behind each other to prevent anyone having any ideas. Unfortunately esp. for NYC it is not unreasonable to expect this to also be an issue for day to day.
