As a lot of people are less and less aware of their surroundings when driving or parking in, they need more essential "Luxury" additions like automatic parking aids, sensors in all directions so they don't hit something around them, automatic brake sensors as they are not aware of vehicles in front of them slowing down rapidly, night time vision display as some are night blind and so on.
One only wonders how so many people where able to drive without all this 2 decades ago safely and with sometimes less accidents then recently...
