If you're using Apple CarPlay, don't upgrade (yet?). On iOS 11 it cannot even keep up playing music without glitches. Crashed twice on me when receiving a phone call. Never had those issues on iOS 10.3.
Rebooting helps. Feels like trying to use Windows on a cheap desktop to watch an HD movie in 2001.
