While driving home from work I experienced my fourth or fifth malfunction error flashing across my digital display. It scares me because this time is different. This time the flash made the seat vibrate and before I had a chance to react, I totally lost control Of my steering even though I had my hand family placed on each side of the wheel none of my maneuvers resulting in the tires moving in any direction. I was trying to straighten myself out but the trajectory Steered me to the right side of the road and up over the curb which tore out my front end And, had it not been for my superb braking skills, id be headfirst into a big cement hole on the side of the road. Brakes We're locked out until I pressed on them 15,000 times it seems.
