With the summer holiday just around the comer, it seems like everybody is busy planning their vacations. Here an some tips that can help you enjoy your holiday without emptying your pocket:

Travel off-season

Go to your desired destination while the demand is low and take advantage of huge discounts. During the peak season, the hotel and flight prices increase quickly, and you’ll likely spend more of your vacation time standing in line due to the rush of tourists.     1

Websites can help you find discount hotel rooms. Look for places that do not charge extra for children if they use the existing bedding. Stay with the locals. If you and your family are going to stay for a longer period, renting a small apartment is a good choice.

Eat like a local

Why eat at big chain restaurants when you can experience something new?     3     During your family trip, try new food where the locals eat. This will not just save money, but also provide you with a new and different experience. For smaller meals and snacks, avoid restaurants and try street food or other takeout.

Don’t hesitate to bargain

Tourist- heavy places are known for overcharging for just about everything. Clothes, travel goodies, souvenirs, etc. are very expensive at these places.     4     Bargain hard to get the best price.

Choose local transportation

    5     Instead, take buses, railways or subways, which are always cheaper. If you are planning to stay for a while, you can consider renting a car. Hiring a car is much easier than carrying your bags everywhere if you are moving around a lot.

【推荐2】Several studies in recent years have suggested that ride-sharing services like Uber and Lyft can worsen traffic problems in cities, which continue to have high rates of private vehicle ownership.

Recently, a new study has found that ride-sharing services result in much more pollution than other kinds of private and public transportation. Ride-sharing trips also draw passengers away from more environment-friendly methods of travel, like public transportation, walking or biking, the study found.

The new study, carried out by the not-for-profit group Union of Concerned Scientists, represents an attempt to center on how ride-sharing services affect pollution. The research examined the effects of ride-sharing services on seven of America’s largest cities.

Overall, the researchers reported that ride-sharing trips now “result in an estimated 69 percent more climate pollution on average than the trips they displace.” The study notes that the same passengers could have chosen to travel by bus, train, bike, scooter or on foot.

One of the big reasons they give for this result is that ride-sharing vehicles are often driven with no passengers in the car. This happens when drivers are either waiting for rider requests, are on the way to pick up passengers or are driving in between pickups. This situation, known as “deadheading”, takes up about 42 percent of all ride-sharing driving activity, the study found. The researchers said that deadheading results in about 50 percent more carbon dioxide than one person driving in a private vehicle. Both Uber and Lyft do offer a choice of a “pooled” ride, which involves drivers picking up additional riders during the same trip.

The study urges services like Uber and Lyft to work to increase the number of pooled rides. It also urges the two companies to increase the number of electric vehicles on the road and to improve connections to public transportation centers.

Both Uber and Lyft have said in the past that most studies on the subject overstate the effects of their services on pollution. They have noted that the majority of vehicles on the road belong to private individuals or companies. Uber told Reuters news agency in a statement it had no comment on the latest report. But the company said it aims to be part of the solution to address climate change by working directly with cities. The statement added that Uber would continue to promote pooled trips and other means of transportation.

The proposal attempts to deal with what some call the “death valley” of autonomous vehicles: the grey area between semi-autonomous and fully driverless cars that could delay the driverless future.

Dobrindt wants three things: that a car always chooses property damage over personal injury; that it never distinguishes between humans based on age or race; and that if a human removes his or her hands from the driving wheel — to check email, say — the car’s maker is responsible if there is a crash.

“The change to the road traffic law will permit fully automatic driving,” says Dobrindt. It will put fully driverless cars on an equal legal footing to human drivers, he says.

Who is responsible for the operation of such vehicles is not clear among car makers, consumers and lawyers. “The liability (责任) issue is the biggest one of them all,” says Natasha Merat at the University of Leeds, UK.

An assumption behind UK insurance for driverless cars, introduced earlier this year, insists that a human “be watchful and monitoring the road” at every moment.

But that is not what many people have in mind when thinking of driverless cars. “When you say ‘driverless cars’, people expect driverless cars,” Merat says. “You know — no driver.”

Because of the confusion, Merat thinks some car makers will wait until vehicles can be fully automated without human operation.

Driverless cars may end up being a form of public transport rather than vehicles you own, says Ryan Calo at Stanford University, California. That is happening in the UK and Singapore, where government-provided driverless vehicles are being launched.

That would go down poorly in the US, however. “The idea that the government would take over driverless cars and treat them as a public good would get absolutely nowhere here,” says Calo.
