Groceries are an issue but basically every truck I have ever had the displeasure of parking near just opens their passenger door all the way (almost always dinging the car next to them) and takes twelve minutes to load three bags.
This just made me think of a great feature for all these cars with sensors nowadays.
Side door ding avoidance - as the door is opened if it detects its about to hit another vehicle, it will halt the door opening.
Of course now you need all the fancy tech in the door to halt the door but think of all dings saved!
