Does speeding save time? Speedr - Android app that measures time saved speeding.
Hey Rennlist, I just created an account to share an Android app I made that Porsche enthusiasts may be interested in. It's called Speedr, it measures how much time, or how little time, you save by speeding. It's free and has no ads. Check it out and let me know your thoughts or suggestions for the next version.
On a serious note, how do you compute this time? Do you get a route time estimate from a Google Maps API and then record actual time traveled? Or do you just integrate x*(1/v_sl - 1/v_s) = \DeltaT, where v_sl is the speed limit velocity and v_s is actual speed?

The app uses GPS to get your current speed. It then sends your lat/long to a 3rd party service that has a database of speed limits to get the current speed limit of the road. Then, once per second second it calculates how far you've driven at your current speed, and how long it would have taken to drive that distance at the speed limit. The difference is then tallied up. Here is the relevant code snippet.

Ok, makes sense. That would ignore the negative effects of being stuck in traffic, which is good.
When do you plan on seeking VC funding, and what is your initial valuation, $100m or a cool $1 billion?? Will you develop your own autonomous vehicle program to limit risk from self driving cars???

That's exactly the idea. Being stuck in traffic is not due to the will of the driver. Only the time the driver chooses to speed is tallied.
Initial valuation needs to be bigger than Uber to develop the planned self driving cars
