I had an original ZS, which had a pretty basic infotainment system. However, it responded marginally quicker than the Ioniq 5 on start up, we can be driving for a minute before we’re allowed anything other than the compulsory warning. Once started, though, the delay between selection and action was biblical, as in 40 day and 40 bloody nights in some cases.
They’ve sorted that to a great extent and the newest, highest spec car will have the best they can deliver, then it’ll be no worse than you’ll get from many legacy manufacturers.
I'm Autistic, if I say something you find offensive, please let me know, I can guarantee it was unintentional.
I'll try to give my honest opinion but am always open to learning.
