I have nothing but respect for the truck driver. Sure, they can be annoying in traffic and when in a small car, downright scary. But! Without them, modern society wouldn't exist. How do you think your food and other goods arrive at the stores?
When you think of it, it makes zero sense to scrap older cars in favour of newer ones because of government say so. On the surface, they new emit less toxins into the air and use up less fuel (unless it was an old diesel, those get better fuel economy compared to petrol cars), but we're talking about a car that's already build vs pumping out new ones. We have to have new cars or else these automotive businesses would out of business due to lack of interest. Face it, we're always going to want better and better. However, for bigger machinery, if it still works properly..it'd do less harm to the environment retrofitting instead of scrapping and building a new one. The new one may be more efficient, but you used more raw materials to replace something that wasn't entirely broken.
