What about making a ball out of rope? You can get hemp rope or even make it yourself if you’ve got a lot of time to spare. You can have a rubber core so it’s squishy and a rope shell to protect it, if she wants a squishy ball. Or make it completely out of rope so it’s more durable but then it depends if she would like it.

Just one more lane bro and we fix traffic, trust me.

The sort of people that ride the bus and train is most of the population in the EU and a lot of other countries.

Reduce 27 lanes to 4 lanes with bus priority lanes and put people on a bus. Thats 27 cars with 5 people in roughly 2 buses with ~50 people.
