9 . Vehicles on our roads are now mostly petrol and diesel (柴油) cars, but their days cannot continue for much longer. A recent university study found that current electric cars could be used for 87 percent of daily car journeys in the US. That figure could rise to 98 percent by 2020.
One hurdle to the widespread adoption of electric cars has been “range anxiety” — drivers concerns about running out of electricity on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. That said, charging points are becoming increasingly common throughout the USA.
Attitudes towards electric vehicles have changed greatly over the last few years. Not that long ago, electric cars were met with distrust, and their high prices drove customers away. Thanks to improvements in battery capacity, recharging times, performance and price, the current generation of electric cars are starting to persuade picky consumers. Plug-in cars will soon give internal combustion engine (内燃机) models a run for their money.
As well as development on the road, electric vehicles are taking to the seas and skies. Electric boats are among the oldest methods of electric travel, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric air travel are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make commercial electric flight a reality.
Electric vehicles do not produce any emissions (排放). If the US could replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 percent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim (声称) to be completely emission-free. That said, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

10 . Tesla’s self-driving cars have recently come under investigation as a report on crashes raises questions about their safety. Despite Tesla CEO Elon Musk’s claim that their Autopilot capability makes their cars “ extremely safer,” data suggests otherwise.
According to The Washington Post, the number of deaths and serious injuries associated with Tesla’s driver-assistance technology is higher than previously reported. The National Highway Traffic Safety Administration (NHTSA) recorded 736 crashes since 2019, with at least 17 of them being fatal. These figures include crashes involving both Autopilot, which allows cars to drive on highways without human intervention(干预), and the newer Full Self-Driving feature, which extends automation to city streets. However, these statistics can’t record incidents that were avoided due to the cars’ safety features. Additionally, when compared to the total number of car crashes that occurred last year, the number of crashes involving driver-assistance vehicles appears relatively small, but actually it’s not.
Tesla’s safety claims lack context as Autopilot is primarily designed for highways, while most accidents occur in more complex environments with cross-traffic, pedestrians, and cyclists. Moreover, Tesla’s customer base consists mainly of wealthier individuals who live in communities with lower accident rates.
Concerns are raised by Tesla’s request to the NHTSA not to reveal whether Autopilot or Full Self-Driving was in use during fatal crashes. This lack of transparency (透明) prevents a comprehensive analysis of the incidents and raises questions about responsibility.
Safety exaggerations combined with Tesla’s aggressive marketing have led to accidents caused by drivers relying too heavily on the system. Full Self-Driving does not allow the car to fully drive itself, and drivers are expected to remain attentive and ready to intervene at all times. However, Tesla’s messaging may mislead some users into believing otherwise.
While a driverless future has the potential to be safer, it is crucial not to convince the public that underdeveloped capabilities are ready for widespread use. Tesla should address past problems, ensure their automation set can detect(检测) emergency vehicles, and be transparent with the public about the limitations of their technology.
