In Car play (UK), the lower right popup menus have options that are horizontal, this makes pressing them while driving awkward, as you need to twist your finger sideways to press the right option, could the option boxes be made either square(a bit larger) or vertical rectangles next to each other, allowing a more natural tap to use.
Also the latest version of the App seems to have moved the destination selection options all over the place some on the top toolbar and some on the map. The previous toolbar with all destination options along the top was much more sensible and obvious. I tried to select my work destination yesterday, and got a popup asking if I wanted voice alerts or full route speech !!!
