I would be curious to see how/if it brings down speeding if they don't get a choice at all but just have to wait. It's not very practical but I do think it would work in principle.
that's how I read that. this experiment specifically gave a choice to study which penalty is more popular, which is probably inversely related to its effectiveness.
