Accidentally applied parking brake whilst driving

Because I can’t believe there are people on the road that do not understand the basic controls of their car.
I think that asking about the peculiarities of an electronic parking brake is fair enough. I've been driving for 40-odd years and know full well how brakes work. However, my (very) new car is the first I have owned with an EPB and I made sure to read the manual to understand it because it isn't as intuitive as the old-fashioned ones. Give the OP a brake. (Pun intended).

If you hold the switch up it will gradually apply the brakes until you slow to around 5 mph then they will lock on, a quick flick of the switch won't do any harm.
Interesting, I’ve always wondered this. Much like flicking into park a few milliseconds before stopping, or letting the gas run slightly before pressing the ignitor on the hobThe really terrifying thing is that megaflow operates a laptop without understanding that there is a thing that should link the brain to the fingers to prevent stupid sarcastic comments..
Do you honestly believe that you should understand the full inner workings of every piece of equipment used in daily life in order to qualify to use it?

When other people’s lives potentially depend on it, yes I do!Do you honestly believe that you should understand the full inner workings of every piece of equipment used in daily life in order to qualify to use it?
I'm sure some tattooed bozo on you tube has tried all these things for the benefit of mankind.
What happens when you ............
........put the car in P at 70 mph ?
........ put the car in R at 70 mph ?
,,,,,,,,turn off the engine at 70 mph ?
.........throw your Keyless Start remote out the window at 70 mph ?
My manual says the Park Brake should only be used in an emergency to stop the car, routine use will damage the system.
It also says if you turn the engine off while driving the transmission will shift to N until slow enough to shift into P.

Thanks everyone for your help, given me peace of mind
Top Gear on Youtube at 120mph https://www.youtube.com/watch?v=9RCFfThqbe8Most EPB's are using the same pads and calipers that the rear brakes utilise for normal braking, instead of a cable linked to the handbrake lever, there is an electric motor or two operating those self same pads, so had you pulled on the traditional handbrake the effect would have been the same.
As said, might be a little bit of extra wear taken place but otherwise wouldn't give it a second thought.
On some car designs (i personally prefer) the parking brake is a different system entirely from the footbrake, utilising small brake shoes on a different friction surface of the rear discs (usually called the drum inside disc design), most people familiar with how they work apply the manual parking brake gently whilst driving every now and again to clean the drum friction surfaces up otherwise they can get quite an accumulation of rust as they never get used when the car is moving in normal driving.
This isn't needed obviously on cars that utilise the rear pads for both footbrake and parking brake.
Previous incarnations of Outlander used the drum inside disc design i described.

It is not a parking brake. It is a brake.
The primary use these days is for parking, but that is because modern brakes are so reliable that is not needed during driving. The primary reason for it being fitted is a back up for use in emergencies if the foot brakes fail.
Serious question, when did you pass your test and how did you pass it not knowing this?
Why post the final sentence? The primary use these days is for parking, but that is because modern brakes are so reliable that is not needed during driving. The primary reason for it being fitted is a back up for use in emergencies if the foot brakes fail.

Someone on the Nissan Leaf section of SpeakEV reported accidentally stamping on the parking brake pedal in an emergency. The pedal as a ratchet and it locked up the wheels irretrievably which led on to some other mishap that I cannot recall. Having a pedal located roughly where a manual transmission car would have the clutch pedal is fraught with risk that this might happen IMO. It is mounted higher than a clutch pedal might be but size 12s will still find it in a panic.
