Which is a perfectly good feature. But a system that just does that sounds like it's a safety backup system, not something that makes driving easier.

> Also "active input" is possibly a bit of a stretch. The system checks whether you are providing some force "against" the motion of the steering wheel. It's not trying to steer away, it just tests if somebody is actually having a "strong" (another stretch) grip on the wheel.

Okay, this gives me an entirely different impression then. To me "active input" means I'm following the lane. If I just have to keep a grip then I don't have to do the work and there's a clear value.
