There are cars made out of aluminum that are designed with safety in mind, like the 1980s Mercedes cars. But nonetheless, government doesn't always know (or care) what's best for the citizens, because they are bureaucrats.

I agree with Stossel on why we should have limited government.

And while I support the idea of using alternative and renewable energy (solar, hydropower, wind, etc.) in some form, NONE of these are practical enough to replace the current energy source we have right now (like nuclear power). Solar takes up too much space, and batteries degrade over time. At best, they can serve as a supplement to the existing energy sources many have. It's actually good to try out new ideas.

But our government doesn't necessarily know engineering too well! All they know best is to take away people's freedom.
