What if the car waiting patiently behind a parked bus is a driverless or autonomous vehicle (AV)？Will this robot car be able to understand what you mean when you flash your lights or madly wave your hands？Its nsors could decide that it's only safe to overtake when there's no oncoming traffic at all.On a busy road at schoolhome time, this may be never leading to increasingly angry pasngers and increasingly angry drivers queuing behind.
And how will a robot car driving out from a Tjunction into oncoming traffic be able to make the necessary eye contact with a human driver？The safetyfirst robot cars could become victims of their own politeness and end up being bullied and ignored by aggressive, impatient humans.This, at any rate, is one of the conclusions to be drawn from rearch carried out by Dr. Chris Tennant of the psychological and behavioral science department at the London School of Economics.His Europewide survey finds that nearly twothirds of drivers think machines won't have enough common n to interact with human drivers.An
d more than twofifths think a robot car would remain stuck behind our parked lorry for a long time.
“If you view the road as a social space, you will consciously negotiate your journey with other drivers.People who like that negotiation process appear to feel less comfortable engaging with AVs than with human drivers，”says Mr Tennant in his report.Of cour, humans are always skeptical about new technologies of which they have little experience.That skepticism usually decreas with usage, however.And even many skeptics accept that emotionless AVs could cau fewer accidents than we humans, with our tendency to road anger, tiredness and lack of concentration.A statistic often repeated is that human error is responsible for more than 90% of accidents.But 70% of the 12,000 people Mr Tennant and his team interviewed agreed that: “As a point of principle, humans should be in control of their vehicles.” An even greater proportion — 80% — thought an autonomous vehicle should always have a steering wheel.

The number of bus, taxis and other vehicles on Kenya's roads is growing every day.Now, the country's first electricpowered motorbikes are coming onto the market.The bike is designed to cut down on pollution and aimed at lowincome communities.Most mot爱迪生是哪个国家的
orbikes ud in Kenya depend on gasoline, but not this new motorbike.
Three university students developed the new ecotran bike.It catches the sun's energy, stores it in batteries and us it to charge (充电) the electric motor.Robert Achoge is one of the student inventors.“Our hope is that by the fifth year, we will be able to cover the whole of Kenya with the electric motorcycle so as to protect the environment and provide affordable transport.”
The students have t up a charging station for the motorbikes in Nairobi.The small battery can run for 70 kilometers when fully charged.Once the power is ud up, the motorbike has to return to the station while another charged battery is connected to the bike.The U．S.African Development Foundation (ADF) is helping t up two solarpowered charging stations in the port of Kisumu.
Each ecotran bike costs about D|S700.One taxi operator says the new motorbike costs less to operate than that running on traditional gasoline.“When it comes to buying gasoline, there's no need.It's basically good for various things.As long as you won't take q
uite a heavy load (装载), you can go with it anywhere.Otherwi, it may break down halfway.But now people still have a preference to the gaspowered bikes.”
A Nairobi businessman Kennedy Kusimba is lling the ecotran bikes.He hopes they will become popular.“We also know they are more reliable compared to the gaspowered bikes.They are more efficient (效率高的) and they will last longer.”
