here is a cosmetic idea to encourage participation in road notifications.

You know how you can have a character as you drive and others can visualize it?

An idea is to make a unique character maybe a bit bigger than the rest of them so other drivers can tell that these drivers in front of them provided an accurate path.

Verification of accurate notifications is if another driver says its still there. With cops is a little different because they move all the time. But you can calculate a ratio of validation per notification to provide the character boost.

Those notifications while using android auto and car play is what makes you guys the most unique.
