I drive a manual, and even if you park it in gear, with some bad luck and a slighly "worn down" engine, it'll roll, so most of the people just pull the hand brake.
if you've parked a manual on a steep enough grade to overcome a worn engine's compression in 1st gear, you're supposed to leave the steering cocked towards the nearest downhill obstacle, preferably against the obstacle before you even exit the vehicle. (usually it's the curb)
When I first moved to CA people would get tickets for failing to do so... but that was when police still bothered doing things. Nowadays I see more cars parked incorrectly than correctly on hills in the bay area.
Hyundai and Kia will automatically engage the parking break if you have auto hold on when you shut the car off.
Why they don’t always auto engage the parking break is beyond me. It automatically disengages when you apply throttle. Most people would literally never notice it being applied.
I've seen a few electric vehicle models with automatic parking brakes but they literally have to use parking brakes to prevent rolling (they typically have fixed reduction gears). It's somewhat unusual on combustion cars to have automatic parking brakes.
Out here in europe, they usually come with the "second cheapest" (and more expensive) options when buying a car (so the base model doesn't have them, but one "level" higher, you get the automatic parking brakes, automatic AC, cruise control, etc.).
They're usually a pain, because if you want to tow a vehicle with them, you either have to turn the vehicle on, to disable them (not always an option if it's an electrical issue) you have to find the manual release (if the car has one), or in some cases, even remove both rear tires and unscrew a part of a brake assembly.... but yeah... not that odd, with an old renault, you had to remove a tire to change the front light.
Sure, so are on manual cars, but once you go above a "base model" with many cars, you get such goodies like cruise control, automatic AC and automatic parking brakes (which can be a pain to release in case of an electrical failure when towing is needed).
