I don't think the autonomous car analogy is really apt here. For a democracy to be a real thing, the voting process needs to be open, auditable, verifiable. The current trend with any software I've seen around voting has been privatized code that is not inspectable by anyone, surrounded by NDAs, and provides far less in the way of proving results are real than does paper. More people voting and real democracy are probably good things, but without addressing the core auditability of the process _first_, software actually reduces the democracy of the process.
