The difference is that electronic voting is a bad idea in principle, regardless of the implementation. Fully self-driving cars might actually be possible, but probably not with current software and hardware.

Do you mind explaining why it is a bad idea in principle? It feels like if we have a decent implementation (a big ask, to be sure), it would be safer and more convenient than the actual way.

Voting systems have a number of key requirements. To prevent bribes or coercion, the vote has to be anonymous and the voter must not be able to prove his vote. On the other hand, it must be possible to verify that each cast vote has been counted correctly. Finally, the whole process should be transparent and understandable for every interested voter.

These requirements can be easily fulfilled with a well designed paper ballot system. I don't see any chance of doing the same with anything computerized.

But we don't apply this rule to the votes where bribery and coercion are most practical to start with, where there are a small number of voters that can be intensely targeted, and swinging a small number is sufficient to decide major outcomes.
