> adaptive cruise control,

I damn well hope not. The driver is legally obliged to be in full control of the vehicle at all times. How on earth is he supposed to do that if his car accelerates unexpectedly without any driver input whatsoever? And he has no way to over-ride other than to turn the whole damn thing off?

Or equally the car brakes unexpectedly on a motorway without any driver input whatsoever?

(Both usually caused because the car has an internal database and also reads external signs. Throw roadworks into the mix and I've had the car run the pretty much the entire gamut of every legal value between 20mph and 70mph in the distance of maybe 100 yards ... talk about getting confused. Oh, and this is in an area where the City Speed Limit is 50mph.)

My car does both. Fortunately, it's usually on familiar roads and I'm expecting it, but adaptive cruise control is a complete liability. My wife hated the basic cruise control on our previous car. I sure as hell hope she never accidentally activates it on my new car because she'll just lose control ...

Classic feature creep where nobody actually does a risk assessment on each individual creep until we have a major accident ...

Cheers,

And... once again... we've wandered far, far off-topic for the article and LWN. Let's end the thread here.

You reveal a fundamental misunderstanding of what "adaptive cruise control" actually refers to:

On the contrary, the regulatory bodies have done _exhaustive_ assessments (including multiple rounds of public comments) to establish the operational requirements for these systems, and after being widely deployed for the better part of a decade data unequivocably shows them to be objectively safer (ie lower accident rate per distance driven).

...I'll leave it at that.

Whoops - I'm describing predictive cruise control.

But unfortunately, my car provides no way to have one without the other :-(
