LEFT DEALERSHIP AFTER TAKING DELIVERY. DROVE TO STOP SIGN AT END OF APPROACH RAMP TO HIGHWAY, ACCELERATED TO BLEND INTO TRAFFIC, CAR IMMEDIATELY WENT OUT OF CONTROL SWERVED TO RIGHT HIT CURB AND LAMP POST. I WAS TOLD AFTER ACCIDENT BY DEALER THAT TIRES NEEDED TO BE WARMED UP FIRST OR CAR HAS VERY POOR TRACTION. THIS WAS TOLD TO ME AFTER THE FACT BY MANY DIFFERENT SOURCES. *AK
