I'm just thinking why would I want a technology active that works on a fraction of the parameters available to me as a driver? I'm not anti lane departure warning when it's just that - a warning (such as vibrating the steering whel), but when it intervenes that's another matter. E.g. you swerve to avoid a cyclist, the system detects you've crossed a line without indicating and swerves you back - straight into the cyclist.

There's also the argument that at this stage of early autonomous driving technology, you're potentially dumbing down drivers. How many will not bother to look and just change lanes in the belief the car will act if there's a problem? What about the other drivers who have to react to this sort of behaviour?
