Yes, Google maps navigation has it. As I approach an intersection, from which there are more than one possible (and already calculated) routes, it shows a message "xy minutes longer trip", or something like that. Good for deciding whether take alternative route on a worse/more dangerous road if it saves only a little time.

Great one. Too add, Waze should have a record of my most common routes between my favorite destinations. Don't re-route from one of the commons routes unless it exceeds this tolerance. Driving through unfamiliar streets and neighborhoods adds undue stress to my commute in order to save 1 or 2 minutes.

A sliding scale that allows the user to set their preference between saving time and going on back roads vs spending more time in traffic but staying on main roads i.e. if I am not in a rush I am happy to spend a bit more time in traffic on a main road instead of taking a diversion over speed bumps etc just to save a few minutes.

On the "fastest" setting Waze is suggesting I turn right only to make an immediate U-turn when I could just wait at the light a few more seconds and turn left. Add a new mode that compromises between Fastest and Shortest called "Simplest.

Create a "minimum time saved" threshold for using toll roads. For example, I may not be willing to take the 407 in Toronto if I only save 5 minutes, but would definitely take the 407 if it saved me 15 minutes or more.

Agreed - There's alot of similar suggestions out there. The other night, Waze took me off the highway in the pouring rain and cutting through some unknown residential areas before putting me back on. I don't know IF there was something major on the highway or not. But I'd be willing to sit on the highway for an extra 10 minutes instead of navigating the small roads.

Today, Still light out; no rain. It really wanted me to not get on my usual ramps to the highway. I was feeling stubborn, and only added 2 minutes. Time "saved' through residential isn't always fully realized.

Besides the faster and the short routes, should be avaliable a simplified route, in which there is a minimal amount of curves. The streets of my city were not planned. They are a complete mess! Its very stressful to deal with. Simplified routes will provide a best experience.

הווייז מאפשר בחירת מסלול קצר בזמן או במרחק -
אני מציע אפשרות שבה ייבחר מסלול משני באם והזמן שהוא חוסך הוא גבוה במיוחד (נתון לשיקול הנהג).

לדוגמה:
אם אני רוצה לנסוע מהרצליה לנצרת וברירת המחדל שלי הוא כביש 2 והוא אומר לי שבכביש 4 אני מגיע בתוך 60 דקות ובכביש 2 ב62 דקות - הווייז לא יציע לי את כביש 4 אלא יישאר בברירת המחדל - אלא אם אני בחרתי אחרת.

ניתן כמובן בהגדרת כל מסלול לבחור את ברירת המחדל שאני רוצה, את זמן העיכוב שבו אני רוצה שהווייז ישנה בגללו את המסלול וכדומה.

have an option not to change a route unless there is at least a (user input=4 minutes) so it will not take you off major roads and re-route on minor roads or neighborhoods

Add the option not to re-route if in doing so it does not save more than 5 or 10 mins travel time. I find that Waze will re-route to save just a few minutes which can sometimes not be worth the effort.

Bonjour,
je partage cette remarque, pouvoir insérer plusieurs "via" seraient vraiment un plus.

It would be great if we can chose how longer way we go against time saved. Very often I got fastest route is 30 miles longer to save 5min. I wish I can chose ratio of max miles over time saved;
example
to save 5min on route no more than 5 miles longer then shorther distance or I prefer 20miles route in 40 min then 50 miles in 35 min.

Have a simplify option for routes. For instance if you save 1 min by taking 3 turns on smaller roads then ignore and keep a simpler 1 turn route. User could set thresholds in minutes for when to bother. Great app. Thanks.

Just to add- should have google like alternate paths with the time sometimes few mins matters but sometimes not.

It seems to me Waze could benefit from behavioral modes of use along these lines that I can choose to select my preferred mode:

1) Aggressive (Do whatever it takes to cut my time down)
2) Moderate (Only take me onto side streets etc. if it saves me more than X minutes of time)
3) Least hassle route - slow and steady, but avoid major traffic snarls.

very good point

הוספת שדה נוסף: "מספר הדקות שיחסכו כדי להצדיק סטיה מנתיב ראשי". לרכב רגיל ברירת המחדל תהיה חצי דקה. לאוטובוס 3 דקות. אני הייתי משנה אפילו ל 4 או 5. אוטובוס מעדיף כביש ראשי. אין טעם להתפתל אם חוסכים רק דקה או שתיים.

I had something like this in mind: https://www.waze.com/forum/viewtopic.php?f=657&t=113062

Boils down to the same thing, waze gets you places, but you may get routed on ways you don't want to be on.

Enable users to choose how aggressive they want waze to be in finding the 'fastest route'. There are times where I will be routed away from main roads, through slow speed zones, neighborhoods, etc., just to save 30 seconds or a minute on overall drive time.

This leads me to doubt waze when it recommends this kind of crazy routing.

My recommendation is that waze implement an aggressiveness option in the "Fastest" vs. "Shortest" navigation option. Something like:

Use the most direct route unless dynamic routing will save me more than XX minutes.

I would select 5 minutes for myself. If waze can save me more than 5 minutes on my drive, I am willing to take the crazy routing.

I have also an idea like that :
indicating with a number on alternating road in front of you, how many time you lose or win if you take it.
Sometimes it is better to stay in a traffic jam for 1 minute more than use an alternative route.
