Has anyone picked up a new Porsche with the ISA speed limiter, how are you getting on?

Watching YouTube reviews the audible warning goes off one kilometre over the speed limit, so I assume the same zero tolerance applies in miles per hour.

I also counted eight button presses to turn off the systems, which you have to do every time the car is started.

That seems like it would tire very quickly?

I've experienced it in a Cayenne. It had a 5/10% margin and I was surprised actually how unobtrusive it was. TBH e more annoying feature was lane keep assist which seemed to default on, too.

You can program the Diamond button on the steering wheel to turn it off with one push.

And the lane assist is turned off with a button under the cruise control stalk.

That is on a new Cayenne, at least.

They’re going to need more diamond buttons. I don’t mind most things being behind menus but there’s probably 3 or 4 functions I’d like with one button press.

By chance, I've been driving around in a new Porsche courtesy car. I don't know if it has the "ISA" speed limiter, but it definitely has a speed warning system.

The audible warning plays at 1mph over the limit, so stray to 71mph on the motorway, and you'll hear it.

Adaptive cruise control with InnoDrive is still awful, more so now that it brakes hard when it thinks the car is suddenly speeding when it's really just got the speed limit wrong. I also find it quite humorous that the car is so focused on not speeding that it fails to see red lights, pedestrians, or motorcyclists etc.

Then there's the ironically named lane change assist and all the other nonsense that cars come with these days.

These systems aren't polished and are clearly in their infancy; I tire of turning them off every time I start the car.

I personally won't buy a new car with these silly systems installed. Normally buy a new car every 2 years.

All new cars sold in the European Union from 7 July 2024 must have ISA speed limiter tech fitted by law.

Normally easy to turn off, not the same car but on my Range Rover it's two presses of one button on the steering wheel. Would be surprised if it's 8 buttons on a Porsche as suggested above!

It’s actually more than eight bottom presses if you include turning off lane change and the other encumbering systems.
