Door Latch problems of the 1998 BMW 540

The inside door handles of my car (1998 BMW model 540ia) are constructed of low grade / fragile plastic material which breaks during normal usage. Without a handle it is very difficult to exit the vehicle. An extremely hazardous situation results when this handle has broken because in case of an accident, a driver, or passenger, will be trapped in the vehicle. To escape, that person would have to crawl to the other side of the car or to the front/rear seat to open a door. In case of an injury from the accident this might not be possible. This hazardous situation is a result of the manufacturers use of low quality materials in such an important component as the door handles used for emergency exit. A stronger material which is not so easily broken should be used for these parts - such as steel.
