You can say that for any technology. Is dynamic cruise dumb because you could just drive it yourself and what if it fails and you're screwed?Dumb question but what purpose does it serve . Because if I’m sitting there with car on and engage brake hold I’m technically compressing the brakes to allow the car not to drive forward . So only way to disengage brake hold is to accelerate or ? . Because when you look at liability , brake hold or not if it disengages for whatever reason your screwed . If I’m sitting in traffic, etc put it in park . Sorry but I have to say this feature is kind of dumb and has zero selling feature .compressing the brake and failure of the system would leave you with zero movement and just another feature to go wrong and people to bitch at .
You just don't realize how nice it is not to have to keep your foot holding the brake down at red lights and such until you have a car with this feature.
You can also disengage it by firmly putting your foot back on the brake and turning it off.
