for every "upgrade" made in favor of bikes, it negatively affects another mode of transportation, mainly cars. These bike lanes aren't being added to the existing road. They're often being added as a REPLACEMENT for what were existing driving lanes!
NYC did this.
Citylab did a great writup, but to quickly sum it up, adding bicycle infrastructure
decreased automobile delays up to 35%. Cycling increased somewhere around 160%, and buses moved through traffic easier. The biggest loss was around an average of 1MPH for cabs.
Essentially, by removing unnecessary through lanes and replacing them with dedicated turn lanes and cycling infrastructure, everyone's commute got markedly faster and safer.

You don't see 1/100 the level of hatred between cars and pedestrians as you do between non-cyclists and cyclists. Why is that? Oh, because you don't have pedestrians thinking they can run/walk fast enough to be in the middle of the street, and you don't have cars trying to drive down the sidewalk. The problem is that silly little 2 wheeled vehicle in the middle, that just wasn't built to "play nice" with cars or pedestrians.
Remember, bicycles came before cars, by a wide margin. It's the cars that weren't built to "play nice" with just about ANYTHING, not the other way around. Hence why SO MUCH money has been spent over the past two generations to modify our environment to cater to them. And then after all that time and money, we have a runaway greenhouse effect, chronic obesity, disastrous land-use patterns, longer commutes than ever before, and crushing average debt due to the near obligatory purchase of an object that begins deprecating the second you purchase it. There is a very good argument that all the money pouring into maintaining asphalt and traffic control devices is a large part of the reason why our modern civic institutions are underfunded, ugly, and falling apart.
Redesigning our entire environment to cater to motor vehicles was a great, innovative, amazing experiment. Just like modernism and urban renewal. It is an experiment that has horrifically failed, just like it's contemporaries.
As for pedestrians in the street or cars on the sidewalk, under the MGL, it is illegal for pedestrians to walk in the middle of the road when there is a sidewalk alongside it. It is also the law that cars can not drive on the sidewalk. What is blatantly legal is that cyclists have an equal right to take up any travel lane we want. Just like tractors in farm country, or Amish buggies, or wide load vehicles, or mopeds, or pedestrians in areas where there aren't sidewalks. Since the Romans started laying the first modern road network, streets have been for all users. There was only a very, VERY brief period in the history of roads in which the car was king, roughly the late 30's to the 90s. We are now getting back to a period in which it is being remembered that streets are universal transportation infrastructure, not an exclusive enclave of cars.
It's not just drivers that have to modify their behavior and learn how to share. Cyclists also have to learn how to obey the rules of the road and ride safely. The issue is you've got an entire culture raised with the idea of a bicycle as a plaything ("silly", you said?), unlike most of the rest of the world. The learning curve is very steep on both sides of the spectrum, and right now it's at the tipping point.

Also, they are often put in places that make "right of way" ambiguous, such as when trying to get onto the BU Bridge. If I'm crossing Comm Ave at the light, and there are bikers that are just laa deee daaa'ing down their lane while I'm trying to get to the bridge, this becomes a pretty dangerous situation. Mostly for the biker.
It's not ambiguous at all. If the bike lane was a car lane, and the bike was a very underpowered car, what would you do? If there is a bike in front of you and you can't safely* pass it, then match their speed and wait behind. Is dropping your speed from 25 to 7 for a block really going to effect your trip time that much? Especially when chances are you're going to hit a light in a block or two anyway?
*Safely = 4' of clearance handlebar tip to car side mirror.
I average about 16MPH when I ride. Trust me, I hate slow, meandering cyclists just as much as you do. Probably even more, because passing them is far more dangerous for me than you (not to mention that pedaling at speed takes one hell of a lot more effort than pushing on an accelerator). But the law is that senior takestheirtime is in front of me and has the right of way. Do you have a conniption when grandma is doing 5 under the speed limit, or is it just what happens?
Speaking of ambiguity for a moment however, I will briefly touch on an issue that Massachusetts seems to not have addressed. In a car, the "proper" way in which to make a right turn when there is a bike lane to the right is to "merge" into the bike lane, and turn from there. Why is this not reflected in the law or the safety pamphlets that occasionally go out? It would eliminate the whole confusion on cyclists having the right of way to go straight when there is adjacent right turning traffic, and do away with right-hooks entirely (since cyclists would either have to stop for someone making a right, or merge into the travel lane and use the space vacated by the car to safely pass). Ideas?
Now if you will all excuse me, I'm going to go ride my bike downtown in 20 minutes for free. Versus an hour on the T or 40 minutes to drive (not including finding parking).
