Trucks are almost 5% of all traffic in the US (1). But there isn't a great navigation app yet. Waze should create an option / app for truckers.
Editors can give in the following restrictions:
- Closed for trucks / RV's;
- Closed for vehicles longer than X meter / feet;
- Closed for vehicles wider than X meter / feet;
- Closed for vehicles higher than X meter / feet;
- Closed for vehicles with an axle load more than X tons;
- Closed for vehicles heavier than X tons;
- Closed for trucks with hazardous substances;
- Closed for vehicles with more than X axles.
Truckers give in the data of the truck and the max. speed (ETA).
This feature creates a whole new audience for Waze.

Waze should make a sound to alert the driver when they are speeding.

Waze already shows you how fast you are currently driving, and it knows everything about the road you are on, so it should be simple to compare your speed to the listed speed of the road.

Waze has always been about saving time and money for Wazers, and about creating features to attract and keep people on their service. This allows Waze to on-sell quality map data to other businesses, such as Apple. Many other SatNav clients have speeding alerts to save the driver from getting a speeding ticket and to help them to drive in a safe way for the community.

It is great that there are warnings for fixed speed cameras, but there are also mobile unmarked police speed traps around, and more importantly, speed limits have been created to make the area safe for the community. Sometimes it is difficult to notice immediate changes to the speed limit and this is where is where it would be good to get notification from Waze about your speed.

In addition, this would create another way for map editors to earn points, as the jobs that they can currently perform on the areas of the map they have access to become diminised as the road map reaches congruency with the current road network.

for all clients expose an API

for Android expose:

• intents
• broadcast intents
• application shortcuts

for the slightly savvier user this allows accelerated navigation by macro (Tasker, Llama, OmniDroid, et al)

API allows for similar macro- or automation apps on iOS (ipad, iPhone), windows mobile, other platforms surely

instead of

° load waze
° click or swipe to open navigate to UI
° search for address
° select match
° go
° pick route

the macro app could accomplish this in

ONE click

this is employing merely one of a panoply of time saving waze measures

add to wiki and label unsupported should that be waze druthers

exposing more granularity would

° empower users' judgment
° conditional logic
° offload server use
° displace more Google maps/nav "sheeple"

less savvy wazers (and waze) could benefit from the efforts of the more savvy

* apply restrictions not for commercial use to kill market predatory-developers, those who spew poor code to fashion self serving malware or apps which exist primarily to render ads

the more non-commercial participants the

° better crowd value
° preferred word of mouth
° google hemorrhaging
° seize market from social gps (displace glympse et al)

add dead reckoning stir pot gently

accept GPS coordinates as destination

mix in more expansive XMPP integration for those who value communication and privacy. Use XMPP Jingle as PTT (Push To Talk)

then waze is socially adept, privacy conscious **, open protocol embracing PLATFORM with potential for plug-in waze domain expansion

waze ought jump in both feet by implementing mpOTR

XMPP is financially wise, utterly displacing sms as many find mobile bills for smart appliances becoming unjustifiably costly (as texting over sms is often half the bill).

° retain wazers despite economic uncertainty
° niche domination
° pair with SIP SIMPLE (additional texting option), SIP presence, and SIP for conferencing while traveling [in tandem]

Jingle has video potential that would not tax waze cloud.
