Not sure if anyone linked this already. [They have been working on airless tires for some time now](https://michelinmedia.com/michelin-uptis/). I’ve never seen them IRL but the design helps with the harshness and weight issues people have mentioned. It would be cool to not have to ever worry about punctures, or having to periodically inflate them, or pay for maintenance on tire pressure sensors.
