As long as it can be turned off when it malfunctions, why is it a nightmare? At least in the Netherlands, most people are going the speed limit or near it. Everyone stays to the right unless passing. In this case, it doesn’t sound like a nightmare.

Somewhere like the US or where people speed often, yeah, it sounds like this feature could get you killed. Like somewhere like Atlanta, you’d probably get rear ended fairly quickly driving the speed limit on the interstate.
