Hey there folks,
Thanks for your patience while our tech teams were looking into this.
It is expected that the screen should dim and your device will lock when charging. Keep in mind that you can always wake your device by tapping the screen.
You can also disable Autolock or use the Waze integration while you're driving.
However, we really appreciate your feedback regarding this and we'll make sure to pass it on to the right teams.
Hope this helps clarify things! If there's anything else we can help with, don't hesitate to give us a shout.
Have a lovely day :)
