A few years ago the same thing happened to me. There was someone who wasn’t doing to good, on top of the station building on the next stop along throwing tiles and other things off. The operator got some replacement busses, that I couldn’t get as I had my bike. So I just sat there with someone else who could get on as they had their dog. For about 4-5 hours. Sucked allot as I was tired, the dog was cute though.

Would guess they are trying to puncture whatever keeps the pontoons afloat. I know nothing about the bridge pontoons though, but seen plenty of helicopters with lots of holes in them

I really hope in the next few years we see a revolution in short distance transport. Most journeys are less than 3 miles (if I remember correctly, could be 5) a perfect distance for e-bikes, e-scooters and normal acoustic bikes. Hopefully at least some places capitalise on it
