If you have OBD2 information, I think it will accurately notify you of your location when driving underground, in tunnels, or in forests.
I would like you to implement it.

Important thing - navigation in tunnels could be vastly improved by this, when GPS signal is not available, as OBD II contains information about vehicle speed = current position in tunnel can be calculated.

Do it. I'll help.

Great idea. Fuel consumption, alarms, engine conditions etc.

Yes, adding OBDII support would be great.

The simplest but still useful addon would be coarse tracking of the veichle in tunnels and such when there is no GPS coverage.

Then fuel consumption, battery voltage alarms...

The OBD dongle 'TomTom LINK 100' records every car uses even without phone and makes them available to Waze via API, notifies a phone it's in the correct car so Waze can wake-up, notifies Waze in case of car crash + does the same as ELM327.

Even an interface from waze to torque or vice versa that would allow Torques dials to overlay waze would be great, I use torque to monitor my mpg in realtime.

I agree. As Waze is all about collecting info while driving, OBD2 provides interesting informtaion that Waze could use to know whar route+avg speed leads to lowest fuel consumption. If OBD2 can provide the estimate driving distance until fuel tank is empty, Waze could offer stopping at the nearest fuel station.

Since I have yet to find a way to log OBD data in the background while using Waze in the foreground, I wholeheartedly second this proposal!

This is great idea!

Excellent Idea. I had the same thought

This is a very good idea and it could be useful for "a green challenge" - based on fuel consumption, average consumption, acceleration changes, it could calculate green score.

Another funny idea could be "a good driver challenge" - points will be collected only during drive within speed limit :)

Would love this too
