I like feeder lanes, and feel there should be more of them - depending on the specific junction construction and traffic flows. Having a green box perched at the front of the queue of traffic that you can't get to doesn't do anyone any good. But yes you do ahve to be careful using them - as is the case when you are cycling anywhere.
I was particularly impressed to see the wheels of a bus in the box this morning - the back wheels that is. To be fair given the speed the queue had been moving the driver had probably legitimately entered while the light was green and then been caught on the red. But even so, there was a lot of bus sticking out into the road!

good feeder lanes would be a good idea. But the feeder lanes often (I would go so far as to say mostly) put the cyclist in a bad position, especially if they want to use the outside lane.
I regularly use 3 ASLs close to my house. The first one has no feeder lane, just two solid lines, so presumably, by the letter of the law no-one should be in them. The second one has a long feeder lane, which is slightly let down by the fact the width is slightly less than my handlebars. The third has a feeder lane that is less than a foot long. So none, in my opinion, are particularly cycle friendly facilities.
I use ASLs when I am filtering. I will filter in traffic jams so that I get through the lights in one traffic light cycle. I don't use ASLs when the traffic is light - I will just wait in primary behind the last car in the queue. When filtering, I am frequently on the outside where I can be seen - doesn't make huge sense to sweep from the outside to the inside and back across the ASL to the outside again, if I am planning to turn right. Of course each junction is different, so left filtering makes a lot more sense at some than others.
