Road traffic is increasing worldwide. 1 _______. However, engineers are working on Advanced safety vehicles (ASVs) which will be much safer for drivers, other road users such as cyclists, and for pedestrians. 2 _______. ASVs will be equipped with electronic sensors to prevent accidents and to make it safer for people when accidents do happen. 3 _______. Others will warn drivers when they are too close to other vehicles.
4 _______. Electric motors are very efficient and produce no pollution, but they need heavy batteries and their range is limited with current technology. Hybrid cars have both a petrol engine and an electric motor. They save about 15% of fuel. They need batteries but they don’t have to be charged overnight as the motor acts as a generator when the car brakes. Liquefied petroleum gas (LPG) is already used as a fuel. Cars can be converted easily but LPG only cuts down pollution a little. Hydrogen fuel cells may be the long-term answer. They provide clean power but each cell is very expensive.
