Furthermore, the driving UI should be designed and tested for safety in the full range of situations that arise. Few drivers are equipped to do that or to anticipate a future road trip that encounters, say, ice in a mountain pass. Some drivers think they're fine sending text messages on a phone while driving. That's dead wrong.
On the other hand, it would be nice to be able to pick the smaller fonts & smaller map, hide some map details, etc. if some people like that. Otherwise the UI should restore the readability and well-designed maps from before the 2020 holiday update.
