questions about Carplay driving task

Hi,

I have a couple of doubts.

1. Can information layout be used for driving task? In the guidelines is stated "The information template can be used by communication, EV charging, parking, navigation, and quick food ordering apps." (hence, driving task is not part of this list) correct?
2. in the Apple guidelines is stated "driving task and quick food ordering apps are limited to 2 templates". Then, it also says that the tab bar layout "allows up to 4 tabs for audio apps and up to 5 tabs for all other app types". What does this mean? Is it possible to use the tab bar layout with more than two levels of hierarchy within the driving task, or should I use it with a limit of two? Moreover, if the limit is two, do I have to also count the tab bar as one and, therefore, use just one other layout in addition as the maximum allowed number?

thanks
