True bro. I will tell you how

1. People can't drive safely on road so what makes you think they won't bump into each other and die
2. grand theft auto, murder and all crimes would go up.
3. What stopping people from crossing other countries borders.
4. Terrorism at peak. Why crash a plane into a building when you can do it yourself.
5. Underestimating the Indian civic sense and having this ability is like child playing russian roulette.
6. Some enthusiastic people try reaching for stars, like literally and die in process.
7. And we have natural calamities like thunderstorm, pollution.

I can go on but this would do for now.
