Exactly. How it works in Belgium is that there are increasing fines for each consecutive year you don't vote, and if you don't vote in four consecutive elections, then you lose your right to vote for 10 years thereafter. To me, that seems a little bit backwards and counterintuitive, but nonetheless, they see high voter turnout.
Again, I would return to my point that that produces people who have to vote rather than people who truly want to vote.
