Mercury News has reported that authorities in San Diego had to temporarily shut down part of California highways 805 and 94 after leaky grease truck created a mile-and-a-half long oil slick on the road.  The slick caused at least two motorists to lose control of their car and spin out, and caused two others to collide as well.  Cleanup crews used sand to absorb the grease.

WSYR 9 is reporting that some temporary traffic lights in the city of Syracuse, NY are so poorly placed that they are actually causing accidents.  The issue seems to stem from the fact that other lights are placed above the intersection at other junctions, but the temporary lights are mounted to the side, on poles.  The temporary light poles were erected to replace the previous light poles, which were so deteriorated that they came crashing down a few months ago.

O’Reilly Radar reports that Motor Trend has reported that Nissan’s newest GT-R model will contain a speed limiter that uses the car’s built in GPS to determine the maximum safe speed.  On highways, the car will be limited to about 110 mph, but the driver can navigate through menus on the car’s computer to enable a special “race” mode if the driver is at a pre-approved race track.  A sign of things to come?
