Yeah - it's totally awesome a but few things to note to be the devils advocate.

1) It cost around $10 million to get it to this point - that's OK as they have got it working but it's a significant capital spend. 2) It cost $600 USD approx for 1 helmet 3) Once it's deployed, time for another $600 USD - it's a one-use helmet (hey it does save your life)

If they can get the price point down it would be totally awesome and they probably will with time. But until it provides a greater flexion point than the good old $20 bike helmet - it's probably not going to sell to governments etc who would be a huge market for this.

All bicycle helmets are one-use in that sense - if your helmet is involved in an impact, you're supposed to throw it away.

True, but hasn't everyone fallen off of a bicycle without hitting their head? In other words, false positives cost $600 a pop. Perhaps that's totally insignificant. This is without a doubt an amazing accomplishment.
