At 17 I probably know a lot more about politics than most people I know, not to say I'm an expert or anything, most people just don't care much about it. However I think there are a lot more problems that need to be fixed with our electoral system before I even start worrying about this issue anyway.
When you have unproportional representation, one of the causes of which being gerrymandering, in a system that mathematically reduces to two parties; when, even with propaganda-propped parties, most of the population are apathetic and/or unknowledgable about the government, you know something must be wrong. And it is definitely not that me and my peers wouldn't be able to vote at our age.
