We've all been here before, trying to back out of a crowded parking lot having a near miss or even worse, a crash. But avoiding these types of accidents is getting easier thanks to new technology. It could save lives, and money.Back in the day you'd have to turn around look out of the window and hope you didn't hit anything. But now cameras are pretty standard in most new cars. They will be mandatory in all new cars starting this spring. And it's more than just a nice thing to have, it's just one of several technologies that are really reducing crashes.The rear view camera gives you a look at things you sometimes can't see with your own eyes. It eliminates those blind spots.Then there are parking sensors. Those are those sometimes annoying beeps or vibrations in your seat that let you know when your car is getting too close to something behind it.     But what researchers found to be most helpful in preventing rear crashes is the rear automatic emergency braking system. It can detect if something is behind you while you're backing up and can automatically brake if you can't or wont stop.Together, this technology dream team is reducing back up crashes reported to police by 78 percent, according to a new study from the Insurance Institute for Highway Safety.Most rear crashes don't result in serious injuries, but you never know who or what might be behind you. Using this technology could save you a lot of stress and potentially thousands in repair costs. 1503

When I told friends that my wife and I were heading to Johannesburg -- which had just been hit by torrential rain and flooding — for a family wedding over Easter, they joked about how lucky we were to be able to take deep baths and long showers.Like many Capetonians, we've endured months of quick 90-second showers, bucket washes or baths that are only centimeters deep and grey water to flush the toilet or water our parched garden. 447

While not as many Americans are expected to travel for Thanksgiving as usual, 56% of Americans are intending on traveling according to data from Tripadvisor. Tripadvisor says that this year's figures are down from an estimated 70% of Americans travelling in 2019.Tripadvisor surveyed Americans from October 16 to 20, so it is possible increased travel restrictions associated with a rise in cases could scare off some from traveling by Thanksgiving. Many states are telling travelers to quarantine for two weeks before coming into contact with others. The vast majority of those traveling, 76%, say they will drive to their Thanksgiving destination, compared to just 11% who say they will fly.The survey found that 22% are staying in a hotel or vacation rental to practice social distancing from friends and family."Despite COVID-19 concerns, the majority of Americans are still traveling this Thanksgiving. The way in which consumers travel, however, will look very different from past years," said Christopher Hsi, Consumer Market Research Lead Analyst for Tripadvisor. "This year, we can expect shorter trips with smaller groups of people for more intimate, close knit gatherings. Many are taking day trips (24%) or spending one night at their destination. Americans are also continuing to avoid big cities, instead opting for warm weather and beach destinations in southern states. We do see, however, that Boomers are less likely to travel this year compared to last (29% vs. 51%)."Whether Americans can safely travel for the holidays remains up for debate, as many public health experts warn that informal gatherings have contributed to the spread of the virus, which has been killing roughly 1,000 Americans per day in recent days.“Unfortunately, the COVID-19 epidemic is worsening, and small household gatherings are an important contributor to the rise in COVID-19 cases,” the CDC said.The CDC issued guidance for holiday gatherings. Part of the recommendations say masks should be worn at holiday gatherings involving people who are not from the same household, and that guests stay 6 feet apart. The CDC also advises against handshakes and hugs.One public health expert says following these guidelines is dependent on your risk tolerance.“I am very risk tolerant,” Dr. Amesh A. Adalja, a senior scholar at the Johns Hopkins Center for Health Security, said in August. “I am an infectious disease physician. I have taken care of people with the coronavirus. Both of my parents are physicians. I don’t take any special precautious with my parents. I don’t think they take any special precautious with me.“I think physicians might be risk tolerant, but I have not changed my behaviors with people I see regularly, other than if they’re telling me they have a fever, and then I might say ‘stay away’ because I don’t want to be quarantined and not be able to work.”Adalja agrees, however, that there is a risk in attending family gatherings, and while face coverings are effective, they're not a panacea.If you ask Dr. Christopher Murray, the director of the Institute for Health Metrics and Evaluation at the University of Washington, he is opting not to see extended relatives amid the pandemic.“Personally, in our family, we will not have our family get together,” Murrays said about Thanksgiving. “I am particularly cautious. That would be our strategy. Certainly, we have avoided, on a personal level, we have avoided any indoor exposure to friends or family and have restricted any exposure at all to outdoor interaction where we can maintain 6 feet or more.” 3579

Winning nearly billion might cause some to be tempted to buy a fancy car or a huge mansion, but what if you could buy an entire professional sports franchise?If you hit the jackpot on Friday, that would be theoretically possible. The jackpot for Friday's Mega Millions is a lottery-record 0 million. As tickets are purchased, that jackpot figure could rise to close, if not more than, billion by Friday night's drawing. Assuming you did not have to pay taxes, what would 0 million get you in the professional sports world? According to Forbes, if you're looking for an NFL team, forget about it. The least valuable franchise in the NFL is the Buffalo Bills, which is worth .6 billion. Despite lackluster attendance in a small market, Buffalo, and similar markets such as Cleveland, Cincinnati and Tampa Bay benefit from revenue sharing and the league's hefty television rights package. It is a similar situation in the NBA, which has a valuable worldwide television audience. If Mega Millions climbs to billion, that would be just enough to purchase the New Orleans Pelicans. Despite their lack of recent success, the New York Knicks and the Los Angeles Lakers are the two most valuable franchises, according to Forbes. The Knicks are worth .6 billion, and the Lakers are valued at .3 billion. If you're looking to purchase a baseball franchise, your options are limited. The only team worth less than billion is Tampa Bay, which was valued by Forbes at 0 million. Six other teams are worth at or just above billion. In the NHL, you could afford to be picky. Out of 31 NHL teams, only four are worth more than billion. So unless you were hoping to purchase the Rangers, Maple Leafs, Canadiens or Blackhawks, you're in luck. NHL teams are valued less than NFL, MLB and NBA franchises due to its reliance on ticket sales and merchandise on revenues. Buying a soccer franchise in the US is a little more complicated. Although the most valuable team in the MLS is the Los Angeles Galaxy at 0 million, the league is considered a single entity. Instead of having individual owners, it has operator-investors. So theoretically you could purchase the rights to operate any MLS franchise you would like, the MLS technically would own the franchise. Of course one factor not considered is federal and state taxes, which would likely decrease winnings. But even in that case, purchasing an NHL or operating an MLS team is not impossible.  2531
