For those saying that there's no real downside to this

This means forever, for the rest of your life. If you're 20, and considering our lifespans will reach 120 easily by the time we're that age, you'd have to drive a prius for 100 years. Everyone else is flying around the galaxy in space ships and **** ? Prius. Want to learn to fly a plane or helicopter? Oh, sorry, just prius. Prius breaks down 50 years in the future? Good luck every finding another one five decades after they go out of production.
