GOOGLE MAPS WITH STRESS LEVEL?

Nowadays many of us depend so much on GPS devices or smartphone apps to guide us as we hurry from home to work or elsewhere.  It's pretty good, how did we ever live without them?  But they can be better.  How often do you hear Google Maps say "There is an accident on So-and-so Turnpike and traffic is heavy but you are still on the fastest route"?  Or when you look at the options for the few routes you can go from Point A to Point B, the highway option is dark red but is still somehow faster than the local route?  I usually choose the local, slower option.  Or whatever the other option that may not be the fastest.  When there's an accident, if it's not too bad one lane of the say, three-lane highway is unusable.  If you are unlucky to be stuck in that lane, you move slowly toward the wreck and then some a**hole in the next lane will try not to let you in, oh because they are so important.  The stress in such situation must be high.  Maybe some day we all will have biotech equipment on us that feeds the phone vital data like blood pressure etc and based on that the GPS app will also list stress level as a factor for taking so-and-so route.  I know I hate to be stuck in bumper-to-bumper traffic on the highway so even if I have to stop at every red light on the local street, at least with that I can divert my eyes briefly from the sorry sight of traffic jam when I stop at red lights.
