told Live Science that his colleagues in the road safety field are

　　“very enthusiastic” about what they're now calling

　　“an

　　intelligent speed alert”.

　　Other research, according to Paine,

　　shows that 40 percent of all traffic deaths involve speeding.

　　There is also a potentially controversial future use.

　　“Since the

　　system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving，” Paine said.

　　“The system even has the capability to record speeding violations, so parents can

　　monitor their teenage drivers.”

　　本文是一篇说明文，主要对澳大利亚一家公司所生产的一种新型的预防超速驾驶的车载智能装备进行了简要的介绍。
