We've all experienced someone speeding through our neighborhood. But would drivers actually slow down if the city were to lower the speed limit?According to a new study by the Insurance Institute for Highway Safety, it would. The study was done on the streets of Boston, and it found that lowering the default speed limit from 30 to 25 reduced the odds of a vehicle going over 35 miles per hour by about 30 percent.The study also found the odds of exceeding 30 mph fell by over 8 percent, and the odds someone would exceed 25 mph fell by almost 3 percent.The study did not examine how the lower speed limits affected crashes, but the institute plans to study that in their next phase.The authors of the study also say that the number of deaths related to speeding were actually higher on roads where the speed limit is 35 mph or lower, than it is on roadways where cars are going much faster. 900

While the Centers for Disease Control and Prevention is urging Americans not to travel this holiday season, it's clear that many will choose to do so anyway.Between Nov. 25 and Nov. 29 — the height of the Thanksgiving travel surge —the Transportation Security Agency (TSA) said it screened about 4.5 million travelers. While that represented 39% less travelers than last year, it represented the most travelers the agency had screened since the start of the pandemic.With another surge in travel expected for Christmas and New Year's, the TSA has offered some helpful tips when it comes to packing luggage for the holiday season.Packing giftsDo not pre-wrap gifts: Gifts need to be screened like any other piece of luggage, meaning gifts need to be unwrapped if they need to be inspected. The TSA suggests wrapping once you reach your destination, or wrapping in a gift bag.Be sure to pack gifts that contain large amounts liquid, like perfumes, gel candles or snow globes, in a checked bag. TSA allows containers with 3.4 ounces of liquid or less for carry-ons.Snowboards, snowshoes and ice skates can be carried on, but be sure to check with airlines about a plane's overhead bin space. Skis and ski poles will need to be checked.Packing foodHomemade baked goods and other treats can be carried on, but any sort of jams, jellies or syrups are liquids and should be checked if they're in a container larger than 3.4 ounces. A rule of thumb? "If you can spill it, spray it, spread it, pump it or pour it, then it should be packed in a checked bag if the container is larger than 3.4 ounces."Higher-proof alcoholic beverages (between 24% and 70% alcohol by volume) are limited in check bags to five liters a passenger. Any beverage with less than 24% alcohol by volume has no size limit in a checked bag.Mini bottles of alcohol can be carried on, as long as they are less than 3.4 ounces and fit "comfortably" in a single quart-sized bag.Packing electronics Electronics to be given as a gift can be carried on, but remember to place electronics larger than a laptop in their own bin with nothing above or below it.TSA allows drones past checkpoints, but double-check with airlines on their policies about transporting drones.Remember, loose lithium batteries are prohibited in checked bags.

What does defunding the police really mean?From Los Angeles to Minneapolis to New York City advocates are pushing for widespread police reform in the form of reduced police budgets. HOW MUCH WILL BE CUT?So far, American cities are taking a slow approach to the demands of advocates. Leaders in Minneapolis, the site of George Floyd's death, have called for the most significant changes with City Council agreeing to dismantle its police department. Los Angeles' Mayor is calling for 0 million budget cut. Minneapolis' City Council is exploring a 0 million cut. New York City's Comptroller has called on the Mayor to cut the NYPD by .1 billion over the next four years. Depending on the number, cuts to police departments could mean fewer officers and most likely fewer programs offered by police departments. WHERE DO ADVOCATES WANT THE MONEY TO GO?In short, leaders in the Black Lives Matter movement want the money currently allocated to police to be re-invested in communities instead. That could take the shape of city development in an often forgotten part of town or in mental health awareness campaigns. Homeless outreach and improved educational opportunities have also been mentioned. NPR recently profiled an effort in Eugene, Oregon, that dispatches social workers to certain emergency calls instead of officers. Advocates support measures like that as well. WILL CRIME INCREASE?You can't have a discussion on defunding police without exploring the possibility that crime could increase. But there is evidence that crime can actually go down with fewer police officers. A 2017 study found that when NYPD reduced its proactive policing polices in 2015 and 20`14, the number of criminal complaints filed actually decreased in New York City. The Fraternal Order of Police though disagrees. Sgt. Robert Pride, who met with President Trump at the White House this week, said he believes more officers would want to leave law enforcement if major programs were defunded. "That's not a profession I want to be apart of," Pride said. WILL THIS ACTUALLY HAPPEN?Police reform has been talked about before but never on this scale. It will also depend on whether the political pressure on city councils and mayors across the country continue. The "defund" movement is likely in its very early stages. 2316

What’s the difference between a place with patchy shrubs and a lush, wooded forest on Google Maps? In the past, the answer was nothing, they were both the same color of green. Now, Google Maps will be using a wider color spectrum to bring out more details.Using high-definition satellite images from more than 98 percent of the world’s populated areas, Google uses a new color-mapping “algorithmic technique” to translate the information into a more vibrant map.The idea, according to a blog post from the company, is to create a map with more natural features, so users can quickly distinguish between tan beaches and deserts, or blue lakes, rivers, oceans and ravines.The team at Google Maps explains how the color-mapping works. “First, we use computer vision to identify natural features from our satellite imagery, looking specifically at arid, icy, forested, and mountainous regions. We then analyze these features and assign them a range of colors on the HSV color model.”Google Maps has undergone a handful of updates this year in conjunction with the app’s 15th year in existence, including a better sense of depth in Live View, more detailed directions for commuting, and easy-to-find contribute and explore tabs.Still to come, Google Maps is promising an update that will show more details about street width and shape. Allowing users to see exactly where sidewalks, crosswalks and pedestrian islands are. 1424
