7. Safer highways
You're sitting in a steel death machine hurtling forward at inhuman speeds. One slip-up and it's all over.
It's not re-entry, it's rush hour, and it's a lot safer thanks to NASA. Working to reduce the number of accidents caused by aircraft running off the runway, researchers developed grooved pavement, which channels water off the road, preventing hydroplaning. It's since been used in major highways throughout the country, reducing accidents on slippery highways by almost 100 percent.
Now they just need to tackle dudes who hog the passing lane and we'll be all set.
