First, it is due to safety issues. Cutting lanes without signalling may cause traffic on the lane you are entering to crash onto you. Second, it is not polite to do so and will annoy other drivers. If like planets,we follow our lanes, it will avoid road accidents
Those are High Occupancy Vehicle (HOV) lanes. To some, they may be known as carpool lanes. To those who've been caught driving by themselves in those lanes, they may be known as "high dollar" lanes.

You should drive on the right, pass on the left. If there are more than two lanes, you spread out but follow the same principle.
Middle lane at +/- 5 mph of posted speed limit
It is safe to change lanes when you look back and make sure no one is coming. Make sure you put your blinker on.
we should take better precautions about driving and factories should cut down on their manufacturing
It depends how long the intersection is, how many lanes there are, and how wide the lanes are.
Yes, when driving on the highway you should always drive in the right lane pass on the left and move back to the right lane when clear. However, on some highways there are more than 3, 4, 5, 6 lanes in both directions. So it depends on what highway and how the lanes are marked.
Not usually. You could have simply changed lanes. the question said "so you speed up to change lanes"
