Most people are not polite and the giant folded strollers take up the room where 2 or three people could stand, and besides the fact my knees always seem to get attacked by the things , when I really got angry was a couple of years ago a young lady (tweenish) was on the bus sitting in her wheelchair, the bus driver made a turn into the GF this huge stroller goes slamming into her and her leg is bleeding not even Im sorry from the rude stroller owners.When our kids were little, we took our double stroller. We where very conscious of those around us. What we did was, I sat in one seat, my 2 kids(they are 13 months apart) would share the one next to me, and my husband would stand in front of us with the stroller in between him and us. So the 4 of us only took up 2 seats. Or, if we were able to, get the seat that is next to the area with a gap and he would stand with the stroller in the gap to the side of us. We always had it folded up well before the bus came so that we did not waste other people's time. I bit of courtesy goes a long way. But that seems to be lacking now with most people, sadly.
