Watch for stats on rolling resistance, tire weight, impact on suspension / size, and cost before getting excited. Punctures occasionally cause blowouts, and those are awful, but still subject to tradeoffs. If airless tires tank the efficiency of your vehicle you'll think to yourself, "Well, I've never had a catastrophic blowout... and changing a tire is a pain, but isn't that bad." We've used airless for decades, just not in cars. We aren't just waiting for a simpler manufacturing process, there are other constraints at play.
