Replace usual "danger icon" by an icon with an image showing type of danger, easier to identify while driving
It should be an great idea to replace actual "danger icon" by different icons showing type of danger.
With actual one, we can identify a danger, that's great, but while driving, it is sometimes difficult to handle smartphone to identify danger origin.
"An image equal 1000 words", so just have a look on smartphone display is better than handle to recognize type of danger !
Yep, pretend you are driving in a highway using waze and you see the stopped vehicle in the road, it should show the stopped car image in road.
