再论frame － 有人问什么中档车有frame？

(During daytime, I'm at client sites. I'm able to login to WXC but somehow unable to post messages. I knew the client is using websense, and I can post to other websites just not WXC, any clue how to hack it?)

很简单，RWD cars 都有frame。不要小看这个玩意儿，车祸时事关重大。除了侧面冲撞 unibody car can be cut into pieces, in head-on accidents, unibody can be deformed and driver can be hopelessly stuck inside.

You can think of race cars. Recently I saw a scene that a car was hit and lost control in the middle of race tracks, frogged and flipped on to fence then bounced back to mid court. Amazingly the driver walked out unharmed. Why could that be? It's about frame - not only under frame, but also upper frame - many metal bars were welded into a nest to protect the driver inside. Aren't you convinced?
