YPSILANTI, Mich. — One entrepreneur thinks flying cars will one day change the way Americans travel — even though his creation almost cost him his life.Sanjay Dhall, the founder of Detroit Flying Car Company, is still recovering from a December crash at Willow Run Airport in Ypsilanti. Dhall said he was testing out the controls in his flying car prototype when he accidentally took off and found himself 150 feet in the air.“It was a miraculous escape. I did break a lot of bones from head to toe,” Dhall said. “… But amazingly the machine took the majority of the impact and I survived.”The machine was destroyed.“One wrong calculation can mean the difference between life and death,” Dhall said. He says he now is more committed than ever to getting the technology right.“I still want to get back and build another prototype, a demonstrator vehicle that will succeed,” Dhall said.A study released this week by the University of Michigan motivates him. It found that for trips of about 60 miles and longer, a fully-loaded flying car carrying a pilot and three passengers had 52% lower greenhouse gas emissions and time savings compared to ground-based gasoline powered cars with an average vehicle occupancy of 1.54."Consumers could be incentivized to share trips, given the significant time savings from flying versus driving," The study's author, Akshat Kasliwal, said.The study found flying cars would travel the 60 miles much faster, resulting in a time savings of about 80 percent compared to cars driving on the road.When compared to electric cars, fully-loaded flying cars still had 6% lower greenhouse gas emissions on trips longer than 60 miles.“When flight happens, constraints are gone. And when constraints go away things have a way of going cleaner ways,” Dhall said.The study did find that on short trips, it is more efficient to stay on the ground.Dhall points out that his prototype features wings that retract into the vehicle, allowing travel by road or sky. In theory, he says it could be an overall greener way of traveling.He says he named his company in honor of the Detroit inventors who changed the way people around the world travel.He believes flying cars will do the same in the future. 2229

SAN DIEGO (KGTV) -- A potential partnership between the San Diego Unified School District and UC San Diego could help prevent the spread of the coronavirus within the school district.On Tuesday, officials with SD Unified and UC San Diego will discuss a collaborative effort that will provide COVID-19 testing -- with rapid results -- for district students and staff members every two weeks.Under the proposed testing program, all students and staff would be tested even if no symptoms are shown. The plan is to get their more than 100,000 students and 15,000 staff members tested twice a month.School Board Vice President Richard Barrera said, “We can’t wait for the federal and state government to provide so we can reopen our schools. We have to take the initiative ourselves ... being able to test on our campuses both students and staff is the best way to get large numbers of people being tested. UC San Diego would bring health professionals onto our campuses to do the testing.”San Diego Unified School District schools are currently in Phase One of the district's reopening plan. Under Phase One, which began Oct. 13, teachers have returned to campuses to provide appointment-based, in-person instruction for elementary school students identified as having “the greatest needs.”Phase Two of the district’s reopening plan would begin for elementary school students on Jan. 4, 2021. Middle and high Schools will start Jan. 25, at the beginning of the third academic quarter.SD Unified Superintendent Cindy Marten, district School Board President Dr. John Lee Evans, and UC San Diego Chancellor Pradeep K. Khosla are among the leaders expected to speak on the proposed partnership on Tuesday on the UC San Diego campus.The school board will vote on the million testing plan at its regular meeting Tuesday afternoon.The district wants to use the million from its budget, which includes funding from the CARES ACT to put up the initial costs to start up this program. But what happens next?"To sustain it -- it will require significant investments and that will need to come from the next stimulus package," said Barrera. 2140

(AP) -- Bigotry toward Asian Americans and Asian food has spread steadily alongside the coronavirus in the United States. Distorted information about the virus that first appeared in China has led to a revival of century-old tropes about Asian food being dirty. Social media has been flooded with racist memes portraying Chinese people as bat eaters responsible for spreading COVID-19. A coalition of advocacy groups said earlier this year that it had received more than 2,500 reports of hate and discrimination against Asian Americans across the country. In addition, Asian American businesses have been among those hardest hit by the economic downturn resulting from the pandemic. 690

 The backlash against electric scooters shows some sign of waning as cities that cracked down on the startups begin thinking maybe they aren't so bad after all.Cities across the country moved aggressively to rein in, and even shut down, companies like Bird and Lime when hundreds of scooters filled their streets and cluttered their sidewalks seemingly overnight earlier this year. Many impounded the scooters. Some levied fines.Yet some cities are softening their stance as they realize scooters can play an integral role in easing congestion, reducing pollution, and bolstering public transit. And the startups, having watched companies such as Uber be penalized for antagonizing municipal governments, are willing to play nicely if it means expanding their market.Austin, Texas, offers a case in point. The city found itself inundated with Bird's sleek black scooters in April. Lime flooded the city with its bright green scooters a short time later."The human response would be, shake off the gloves and let's go. Let's fight this. You just disrupted my city," Jason JonMichael, assistant director of Austin's smart mobility program, told CNNMoney.Instead, city officials talked things over. As it happened, they'd been planning a dockless bikesharing program. Their plan called for eventually adding scooters to the mix, so they decided to work with the companies to make it happen, JonMichael said.Rather than issue a cease and desist letter -- an approach some cities took -- Austin warned the companies that it would confiscate scooters blocking sidewalks. And city officials set to work crafting an ordinance governing a permitting process for scooter services, including speed restrictions and fees for operating.Today you'll find 2,000 scooters all over Austin. People love them so much -- each scooter is ridden nearly 20 times daily -- that their batteries often go dead by noon, JonMichael said. And it's making life better in the city, too. JonMichael said people are taking fewer solo trips in cars, which means less congestion and pollution.The city reviews each company's performance every six months, reserving the right to revoke the license of anyone who isn't playing by the rules. That's got the startups working hard to stay in the city's good graces by offering discounted rides to low-income residents and developing tools that allow people to report bad behavior by anyone zipping along on a scooter.City officials now see scooter and bikeshare firms as allies in their efforts to improve quality of life and expand transit options. The startups are "bringing to the table discussions about developing a roadmap to deploy transportation that from the get-go has equity and access for all built into it," JonMicheal said.Bird hopes to broker a similar alliance in its hometown of Santa Monica, California. The company launched in September 2017 and followed the ridesharing playbook that says it's better to seek forgiveness than permission. Bird launched without proper business licenses, and in February agreed to pay the city 0,000 in fines to settle a criminal complaint.Despite the trouble, Santa Monica officials wanted electric scooters to stay given their focus on multi-modal transportation and carbon-light living. The city gave Bird and Lime conditional permits while it worked to set up a 16-month pilot program. Earlier this month, the Santa Monica government ranked applicants to its scooter program, and Bird placed 10th."That was a real wake-up call. This is a fantastic business, and there's a lot of competitors who want to do it," Dave Estrada, the Chief Legal Officer at Bird told CNNMoney. "It really helped us take a good look at how we were doing operations and how we can best serve cities."That explains why Bird on Wednesday announced several concessions intended to curry favor with Santa Monica and other cities. It will let cities designate no-go areas where people can't ride or park scooters. It will grant cities the option to convey the rules of the road and other safety tips in messages users see before riding off. And it will share data that will help cities understand how people are using its scooters.Bird went so far as to resubmit its Santa Monica application earlier this month, to be more appealing to the government. At the city's request, it has begun limiting the speed of its scooters to 5 mph on the beach path, and in Palisades Park, two areas that have been controversial. It also plans to send text alerts to riders who stray into areas where cities don't want scooters.A lingering challenge for the industry is sidewalk riding, which irritates many pedestrians. The scooter companies instruct customers to ride in bike lanes, but bike lanes are rare and sometimes customers still choose sidewalks. Bird is exploring ways to discourage sidewalk riding, by automatically detecting with sensors when a scooter is on a sidewalk.It may not be popular with every rider, but the startup has realized that cities are its customers too."We started understanding that we had one customer, the rider," Estrada said. "Now we really understand a lot better that customers include cities and people who don't ride Birds." 5222
