Why is the glass so fragile ? I'm sure they used to have a bottom metal frame
It's tempered glass, so it doesn't need the support. It also means that it's designed to shatter in a way that prevents sharp edges. That robot has a lot more power than a human when it hits the glass. Tempered glass does weaken after repeated strong impacts, so that could potentially be part of it as well.
Does the robot have any sharp bits? Tempered glass doesn't require much force if using, say, a broken bit of spark plug.
I would’ve assumed it would be made from plexiglass.
It’s not like shattered bus shelters were a huge epidemic before this so it seems like the city already found a good balance between cost and safety.
