Would raising the driving age have significant ecological benefits?
If the legal driving age in the US were raised to 17 or even 18, would this significantly lower emissions and fuel consumption? I imagine that to answer this question, we’d need to know several facts: How many drivers there are in the US, how many of them are kids age 16–17, how many miles are driven and how many by kids, whether kids are more likely to drive older and poorly maintained vehicles, etc. Obviously, taking drivers off the road will reduce emissions and fuel consumption to some extent, but would the benefits of raising the driving age be worth the costs? I imagine someone has researched this; if not, it might make a good term paper topic for some young jelly.
I’m mainly interested in the environmental effects, but feel free to digress into non-environmental costs and benefits of raising the driving age.
