I test drove an Ioniq 5 and the way the salesman pitched it to me was – if all the disabled spaces were full I could get out the car and use the feature/key to park the car in a standard size parking space from the comfort of my wheelchair
In reality though, if this scenario occurred, where would you stop in order to alight from your car and transfer to your wheelchair, in order that you could then park the car remotely? Doing that in the middle of the car park wouldn’t be practical (or safe).
I can see that this feature would be useful to put a car in and out of a private garage where there is limited width but, as previously mentioned, I don’t think it makes sense in public car parks. If people are parking so close to other cars that they have to use a remote feature, there’s a strong likelihood that this will result in damage to your car when the occupants of adjacent cars have to squeeze into their car, when they will likely hit the side of your car with their door. Having incurred several dents this way myself over the years, I make a point of avoiding narrow spaces as it’s asking for trouble.
