Obstackles from Shenton Road Caremont to Aberdeen street in Perth

These are my obstacles when I cycle to work:
I cycle twice a week from Claremont to Central Institute of Technology in Perth and twice a week to Curtin University in Bentley this semester. I took photos from the cycle path to Central this week and will do so to Curtin next week as semester starts.
This bus sign is the first obstacle I come across when I hit the first cycle path on Shenton Road in Claremont. It's just across Claremont train station.
Why is it build in the path??? People waiting for the bus are on the cycle path and if you have oncoming cyclists you have to stop in front of the sign...
Only a little bit further, when I enter the overpass on bridge to Showgrounds there is the second obstacle; a bollard. And only moments further is the 'dead' corner at the train station where two people collided only a few weeks ago with also serieus results.
Is this bollard there to prevent cars from entering the cycle path? From where? And if they did they got stuck in that dead corner anyway so which sane driver would want to go there?
And at the end of bicycle path along the Showgrounds train station, just before you enter the parking for Loch Street station, there is another bollard in the middle of the path. Probably to warn you that a 90 degree turn is coming up, which no cyclist ever takes as it's impossible. Most cyclists go over the parking and cross the road at the end of the parking. For a few kilometers there is no cycling path.
Until you reach the famous 'blunder-pass' where they've added a bicycle path on the other side of the road, so you have to cross the road and make another 90 degree turn to get onto the path. Also coming from the other way it's not easy to make that 90 degree turn back onto the road as oncoming cars don't like it to see you coming onto the road. Why didn't they create a more fluent transition like they do for cars?
On the path over the blunder-pass there are two bollards but they are sunken in the ground for now. Not sure why they are there and when they will be errect? This part of cyclepath is maybe one kilometer long and at the end you have to cross the road again to follow your way on the road untill you hit the next part of bicycle path at Shenton Park train station where again you have to cross the road to the other side.

It's not easy to manoevre there as there are a few sets of frames where you have to get in between as well as a few 90 degree corners to tackle. Just a little bit further is another bollard, probably also to prevent cars from going on the path, but where do they want to enter??? It's not logical. So why do we have all those obstacles on a cycle path while they are not good for any cause. In a recent research in The Netherlands they have concluded those bollards are dangerous and cause 12.000 accidents per year and 12 death and that is in a cycle friendly country. Many councils have decided to get rid of the bollards since.
Until Subiaco you have a reasonable cycle path, although the underpass isn't easy to navigate as you don't see oncoming traffic. And the cycle paths are broken up at every road you cross. The path becomes more scruffy around City West train station and I have to pass hundreds of high-school students on the path who walk in thick clouds of people and don't leave any space to pass so you really need your bell. A bit further the bicycle path runs into the huge building site of the Perth Arena. Where builders are on and off through a huge gate but you have to turn right in a squiggle.
And after you've followed the nice graffity wall the cycle paths just suddenly stops since last week. And I've heard from the people working at the Perth Arena that it is going to be like that until at least September because the City of Perth didn't take action on this traffic problem when it was asked by the project managers. They are so smart, just let it sush out itself they must have thougth. Lazy clerks! Now I have to risk my ass to ride around the Perth Arena to reach the bridge over the railway, which isn't much fun with a huge pothole in the road as well.
And when you arrive there you have to find your way in between the building site to get onto the bridge, in between the two frames to go up and when you reach the top there are another set of frames, God knows why??? As it's not to prevent cars getting up there. It's more like to lose your momentum especially when there is lots of oncoming traffic.
I can't believe that cyclists and pedestrians just adapt to those obstacles while it's the most stupid thing. It is totally not necessary to be in that spot. At the end you go down to meet up with another set of frames to prevent you from going along. I wonder what the future will be for this bridge over the railway. I haven't seen any plans or progress since they are building there and that is a really long time now.
My last stretch of the way is through the Northbridge cafe-strip area and the only thing scary there is the weird dark grey pavers, on the new arty round-about on James Street, which are very slippery.
