 So you're driving and taking directions from the voice on your phone. You're on time. Traffic isn't too bad. Then, suddenly, you find yourself at a risky intersection where you're forced to make a left onto a busy, high-speed thoroughfare. There's no stoplight to bail you out. In these cases you sometimes throw caution to the wind and go for it. Other times you're stuck waiting for that gap, while disgruntled drivers honk at you from behind. 
  
 If you use Waze, you're probably a little too familiar with this scenario. The app often encourages drivers to take less crowded side streets to save time, which is great. But the resulting unprotected left turns can be terrifying, and if you get stuck, it doesn't feel like you're saving all that much time. 
  
 Now the sometimes polarizing navigation app is trying to save Angelenos from these scenarios, reports the L.A. Times. The company announced Wednesday that the app will usher L.A. drivers away from tricky intersections that require a left turn. This may come at a cost for drivers, however: the new routes may take longer. 
  
 The app will rely on user feedback to determine which intersections are difficult. So far Waze has compiled a list of about 100 problematic intersections, such as the turn from Selby Ave. onto Pico Blvd. in West Los Angeles. 
  
 For those brave users who laugh in the face of danger, they will still have the option to stick with the original routes, a spokesperson told the Times. The new feature is expected to launch in New Orleans next, reports CNET, though a launch date has yet to be released. 
  
 Left turns have gotten a bad rap in the past few years. UPS actually launched a whole investigation into the matter. Their engineers concluded that it was best for their deliverymen to minimize, or eliminate completely, the number of left turns they make while driving. The effects, apparently, are kind of staggering. According to UPS, from 2004 to 2012 the no-lefts decision has saved 10 million gallons of gas, and reduced carbon emissions by 100,000 metric tons. ||||| Enlarge Image Waze 
  
 It's almost undeniable that left turns are evil. 
  
 Not only are poorly-managed left turns responsible for about half a million crashes and hundreds of deaths per year, but they're also inefficient. UPS, the brown-truck delivery company, famously banned left turns for its drivers in 2004, and since then it's avoided unnecessarily burning more than 10 million gallons of gas, cut down on pollution and probably saved lives (and a few fenders too.) 
  
 Now Waze, the crowd-sourced traffic app owned by Google, is joining in the anti-left-turn crowd by offering a new feature to Los Angeles drivers. Waze will effectively seek routes that doesn't include a left turn, and when it finds one it will calculate to see whether it will cost more time. If not, you're off to right-turn land. The feature is already available and was announced Friday. 
  
 Now, before you get out your pitchforks and scream bloody murder about Silicon Valley's paternalistic "we know better" attitude, users can shut the feature off if they prefer. It'll be in the settings under "Difficult Intersections."

 And for the rest of us, Waze promises we'll still be occasionally vexed by left turns for the foreseeable future. 
  
 "The goal of the feature is to reduce the amount of these intersections, not completely eliminate them," Waze said in its announcement. 
  
 Why did it all take so long? Apparently this isn't something a mere computer can figure out. Waze said it worked with Angelenos who often help edit its maps to determine the worst intersections. And since it needs help from locals, the rollout will be pretty slow. New Orleans will be next, though Waze didn't say when. |||||
A:
Waze, Google's map app, is notorious for forcing drivers to attempt uncontrolled left turns onto busy streets in an effort to get them where they're going in the shortest amount of time. “Many drivers (and especially LA drivers) know the feeling," Waze itself admits in a statement. That's why the app announced a new feature Friday to make commuting safer and less stressful for Los Angeles drivers: Waze will automatically look for routes that minimize left turns while taking around the same amount of time, CNET reports. A left turn can be a “stressful scenario that requires crossing multiple lanes of oncoming traffic," according to Waze. Yet the app routinely leads drivers into them because it prioritizes empty side streets to help users avoid traffic, LAist reports. To solve the problem, Waze worked with Los Angeles citizens to identify problem intersections, ending up with a list of 100 or so. Because the new feature requires the input of actual humans, it will take a while to introduce it in other cities. New Orleans is next. The new feature could do more than make driving more pleasant for Waze users. Left turns cause about 500,000 crashes and hundreds of deaths every year in the US. UPS actually banned its drivers from taking left turns in 2004 in a move that saved millions of gallons of gas and reduced emissions.
