Assistance systems causing dangerous situations (serious)

[Timcat]

The original topic was ‘assistance systems causing dangerous situations’, which I’d say my car going from 70mph to 5mph on a busy dual carriage way definitely constitutes.

I’d be really interested to hear if Porsche manage to improve the situation on your car regarding it, and I do hope they can fix your car, it it would give hope to many of us who are very frustrated that these systems just aren’t up to the job, and dangerously so.

I'll certainly post the outcome of my car's scheduled visit to Porsche!

When using Innodrive's Adaptive Cruise Control does setting the speed manually in your car stop the car from altering its speed in response to speed limit signs? I ask because, this is what I do on the motorway and I have never had the problem you have experienced.

Interestingly, the problem you are having is the same or similar to the phantom braking issue with Teslas, except that phantom braking in a Tesla happens randomly and even when the max cruise speed has been set manually. The braking is often sudden and hard, and has caused serious accidents. I'm curious, does your car apply the brakes hard, like phantom braking in a Tesla, when slowing for a wrongly recognised speed limit?

When you press the mode button on the end of the cruise control stalk, you get to turn on or off which of the three features you want via the central display (speed limit, route topography, lane keeping). I tend to keep speed limit adjustment off as it is regularly incorrect in what it think the limit is. I find the lane keeping works pretty well, unless it is dark and the car is dirty, where I disable it for that drive and use it as a regular adaptive cruise
I am in the same camp as you with turning off the speed limit warning with the diamond button and the lane departure with the button on the bottom of the stalk at the start of every drive

OK so I have an interesting update for those who follow this.

My car was at the dealers to fix the suspension issue and turned out there is a recall / service campaign for my VIN - software update and "sensor calibration". I've noticed much improvement after this, no false positives during parking where I've had them all the time and I think the LKA is much less sensitive / jumpy then before.
