Make Tunnels navigable
In London, there is a tunnel which forks underground. No satnav, WAZE included can get a GPS signal.
It would be useful if Waze could give directions ahead of time when you approach an area or stretch of raod (eg a tunnel) where it knows (from prior users' experience) that it is certain or likely to lose signal.
Additionally, or alternatively, there could be an user-selected option where, when signal is lost, Waze either a) considers the car to have stopped, or b) considers that the car is continuing at the same average speed as just before signal was lost.

This idea was exhibited in Brazil in the first meeting of wazers
This was my presentation http://www.slideshare.net/alvtej/waze-rio
Go to Slide 19.
Dead reaching could be used when in tunnels.

There is one very big issue with this. How does the app track your progress in a tunnel?? The app, like all navigation apps, use the signals from GPS satellites to work out where you are. These signals are not able to reach your phone/tablet whilst you are in a tunnel. Try listening to a radio station in a tunnel and see. How about phoning someone? "opps! sorry, entering a tunnel, losing the sig........"!
I've been stuck on my way to Paris on the A14 tunnel for nearly 1h30. It took me 2h30 while waze suggested 1h for my total trip !
This was the worst suggestion ever.
I don't understand why I didn't get any update from the app since I was able to get mobile network without any problem. A fix is needed urgently for this major issue IMO. I can"t imagine that Waze doesn't see when we get in and when we get out the tunnel.
Yes, Waze reads the suggestions. Check the Wishlist here : https://wiki.waze.com/wiki/Wishlist
Tunnels are entry #14

Navigon / Garmin has a tunnel navigation mode and Waze really needs one too. Especially where you have tunnels - like where I am in Stockholm - as here, we have multiple splits and exits inside tunnels.
Nicolas Bougues has a great suggestion. Waze's inability to extrapolate tunnel conditions leads to bad routing recommendations relating to them (e.g. every time I go through the Boston Central Artery Tunnel my estimated arrival time improves by five minutes as soon as I exit. Also, it's not uncommon to get poor route recommendations because Waze believes that there's significant congestion - frequently routes involve getting off the highway, taking local roads and then getting back on OR driving to a distant highway entrance for no particular reason).

Please consider optional OBD2 reader when present.
This will easily deliver actual speed inside a tunnel.
does anybody read the suggestions????
Nicolas Bougues commented
Couldn't Waze, when it re-acquires GPS signal after loosing it (probably because of a tunnel), just decide of some average speed for the whole "blind" segment (I mean, each sub-segment, based on length).
This would effectively let Waze process congestion inside tunnels (no matter the kind of tricky road connections inside), and stop it from suggesting congested tunnels forever.
Of course this would only work if the exit point of the tunnel is the one on the initially planned route, but in practice this is the case, most of the time.

10years ago my old gps TomTom already knew the solution... Please wake up. Radar caught me in a long tunnel because my position was stopped. So boring...
for two years under review? any solution???
New chips have built-in ability to use the accelerometer and gyroscope for positioning and navigation. See, for example https://developer.qualcomm.com/mobile-development/mobile-technologies/snapdragon-sdk-android/features/location

combine with that external GPS idea .. possibly exterior mounted
and definitely implement deadreckoning as a feature itself in lieu of gps-alternative location sources

That dead reckoning is appealing
Jacob van Dam commented
Elaborating on the post of Wim Godden (below), when being in a tunnel, Waze is disconnected from navigation until exiting it at the end. However, sometimes a change in direction has to be made immediately after the tunnel, but then it is already too late to receive in time the next step. I suggest that before entering the tunnel, which is usually more than 800 m before the change in direction, Waze will indicate the next direction to be followed immediately after exiting the tunnel. If not - current situation- when you exit the tunnel (with approx. 100 km/h), you may miss the turn in time. Moreover, this seems to me also applicable for warnings, such as speed cams.
This is not just applicable to tunnels, but to any place where there is a reasonable expectation the GPS signal will be degraded, such as on the lower deck of the George Washington Bridge (NYC).
NOTE: This could likely be combined with the Dead Reckoning idea.

My daily commute is shorter if I take the tunnel, but it is always congested at the time I drive to work. There are other, longer roads that is faster. Since Waze does not work in tunnels, it does not know it is congested.
