In brief
Managing from a key or a phone does not make the maneuver irresponsible.
Useful to know
Bosch's Remote park assist can perform a parking manoeuvre while the driver is out of the vehicle. The variant described drives brakes, steering wheel, engine and gears, with the movement continuing when the control button is held. [1]
This distinguishes the function from a simple remote ignition. The driver remains responsible for monitoring the surrounding area. In a narrow parking lot, check not only the final position, but the entire trajectory. Possibilities and permitted use depend on the specific vehicle; the general product description does not mean that the function is available in any market or level of equipment.
