Select safer way by following someone if alternative route is similar time
Safely travel means to follow others. Like on festivals inside crowds ==> people tend to walk together = crowd pulls you. Basically we should drive in circles. While road has dashed line, we better don't want to meet many cars in opposite direction. This can avoid mamy accidents by front crash. Similar road arrangement can be seen ie. also on some festivals so it is not just a dream!! I prefer to come 10min late than never [+]. Waze should offer this always (on dashed line roads).

Hint for bit complex Class for segments selection algorithm..I ment someone = TheAverageDriver goes that dashed road in weekday AND in timeframe AND direction. Expected result Main way. Often Highway.
