I don't know NY, but there are plenty of bits of England (or do you mean NYC, in which case I'll pick any large British city) where wide, straight, well-paved roads have 40mph-50mph limits. Generally it's because there are lots of junctions, or people walking alongside the road, or heavy traffic.
The M25 (the 117-mile 4+4 lane motorway around London) sometimes has 50mph limits (the limit changes, depending on congestion -- when it's busy lowering the limit increases traffic flow).
This is because there are too many idiots in this world that don't understand the concept of speeding when you have the room to do so.
If you go over the limit in a traffic congestion period of time (AKA: "Rush hour". not the jackie chan movie, please.) you're bound to wind up amassing behind the heart of the congestion, and perpetuating it's dead stop for the next car behind you (at this point, most likely another imbecile speeding in futility.).
So it was brilliant for the UK to develop speed limits based on hours of the day. It inadvertently gets the law abiding simpletons to give more time to the congestion ahead to dissolve. Because lets face it, you can't expect enough people with common sense to go BELOW THE LIMIT appropriately to traffic conditions.
When you didn't opt for a dataplan, your iphone would still attempt to reach out through 3g for data. This would eventually add up on your bill and they'd make their crooked money by having the iphone ping the datanetwork everytime you brought it out of sleep mode. regardless of whether you were on a wifi, it continuously attempts this every chance it gets.
For those users who didn't want to give the providers money for nothing useful at all, they wanted to use the wifi as the primary means of data transmission. and after changing the api of the datanetwork defaults on the phone to a "fake" one, they were completely free of the bullshit that is normally involved with not signing up for a contract and being alienated by their provider.
these wifi apps empowered the user to make the most out of their wifi on their phone, which made it "easier" to opt out of the seemingly obligated contracts and dataplans. resulting ultimately in less money for the greedy bastards.
So im sure that they all bitched and moaned incessantly to apple crying about how those wifi apps are the devil and the user shouldn't have things so easy. now apple, naturally wanting to "improve" their relations with the companies; fucked the customer's choices because they see very little to no consequence over removing that group of apps.
I actually haven't jailbroken my iphone, because i believe in choice and paying for apps that deserve my money. I have however disabled my 3g data, and don't ever plan on caving in to getting a "convenient" dataplan.
Now that those apps have been taken from me as a choice, i am more prone to consider jailbreaking my phone so that i don't have to bend to whatever whim apple decides to take.
in the end, every move they make to control our choices; will push us to take our freedoms back. and if any developers' wallets get harmed in the process, it's apple's fault.
