Frankly, everything in the last ten pages you can argue there are times and places for a large proportion of it. Heated seat? Well, if it's cold, it's nice to sit on something warm. Wipers on your headlights? A dirty set of headlights can need a clean! Electric seats, mirrors, etc etc all perfectly reasonable.
You want pointless, you only need to go back a few years to the old Nissan and Honda accessory catalogues to find reams of pointless crap. My car <- came with options such as a Purifier;
knee pads that bolted onto the door card and centre console and a parcel shelf speaker system that rendered your boot (Trunk to you Americans) useless. Then there were things like the mirror spoilers;
Never mind all the racing accessories you could buy for your road car including Rally skid plates (just incase you were off roading in your small nissan hatch back) and aluminium foot rests for your front seat passenger. The best one, though, was the thing that Rolls Royce copied; a spring loaded umbrella stowed inside the rear quarter panel that you could access when you opened the drivers door;
genius.
And for you Honda JDM losers, who could forget the springy map light option, the Sunroof Spoiler on early civics, dash pods for your compass and the most hideous drinks holder known to man;
Yes, that really was a factory option.
You would really buy a car with out emergency brake? Not such a good idea! And if yours' doesn't work, it's usually because it wasn't used often enough, during the life of the car. Like the old saying 'if you don't use it, you lose it', pretty much goes with any emergency brake of any type.
