8 on a scale of 1 to 10. SEE COMMENTS ON SOFTWARE IN THE NEXT SECTION.
As a retired software engineer with over 40 years experience, I find the Ioniq's software to be quirky and somewhat awkward to use. Also, since I had a stroke, I don't have fine motor control over the fingers of my right hand. Physical switches (toggle, rocker, or push button) would help as would the ability to create custom voice commands (as long as they are safe and legal). Lastly, when the car is turned off and the onboard software detects a definite shutdown coming, the last thing it should do is take a snapshot of the car's entire memory and a list of functions enabled. This would eliminate the clumsy, time-consuming startup procedures. THE CAR COULD THEN HAVE TWO COMMANDS: START UP OR RE-START. This is not rocket science.
