Sorry, but that is a gross misinterpretation. Drivers are not victims of an intrinsic speed devil that they cannot escape. They still choose to violate the speed limit in most cases.
What was done in these countries is to acknowledge, that physical design is more effective as enforcement, than the cop with a speed-meter.
Still the explicit intent is to enforce speed-limits, knowing that people would violate them if they could, but they can’t because they would wreck their car. Still those people choose to violate and are responsible for their actions.
