Paul Walker - Car May Have Malfunctioned.

The exotic sports car in which Paul Walker violently died, crashed as a result of mechanical failure -- very possibly a steering fluid leak ... this according to sources closely tied to the auto shop where the vehicle was stored and maintained.
The AE sources point to the fact there is a noticeable absence of skid marks until just before the point of impact. They say if Roger had lost control the skid marks would show swerving, but instead the marks were in a straight line. They feel this cements the theory the driver didn't have steering control. Also suspicious -- the fire spreading so quickly in the front of the car. The sources say flames would be expected in the rear where the engine is ... but fire in the front reinforces their theory of a fluid leak of some sort. Cops are investigating the possibility that Paul Walker was in the middle of a high-speed street race with another car at the time. Law enforcement sources tell us ... investigators have received tips that Walker and the man driving the Porsche, Roger Rodas, had been racing prior to the crash ... and the high speed may have contributed to the wreck that killed both men. Sources say ... the area where the crash occurred has a history of being a popular street racing location.
