Very glad this guy's case was successful.
People that get in a flap about having to fold up prams perplex me. I have friends who won't even take the bus because of the risk this might happen 
If there is someone in a wheelchair or another buggy already in the space/wheelchair person boarding I (1) give DS to someone else to hold (2) put any shopping in the seat where I will be sitting or in the bag storage area (3) fold up buggy. And yes I have done this while bus is moving.
In fact often the person in the wheelchair often offers to hold DS or my bag for me while I pack up the bag. And if not there is 99.9% of the time another parent or a coo-ing granny who is delighted to hold DS.
If I am the person in the wheelchair space with my buggy I always offer to hold the child of the person coming on/folding up buggy.
If I am in a big city eg London I always use the sling.
If I have to wake up DS that's just TOO BAD because errr it's public transport innit. I wouldn't tell a pilot of an aircraft they couldn't depart because DS was asleep in his pram at the gate....
