I-€™m reporting this safety concern and seeking advisement from those more knowledgeable than myself on this issue. Recently, as I attempted to actuate the brake of my vehicle. My right foot was entangled with the brake pedal as I moved it from the acceleration pedal to the brake pedal in observance of a -€œStop Sign.-€ I barely avoided what surely would have been a catastrophic collision with another vehicle. The incident occurred in a split second. The shoe of my right foot was entangled with the lower right corner of the underside of the brake pedal, which has a protruding sharp thin metal edge. The sharp thin metal edge impeded the performance my right leg as it dug into my shoe-€™s sole edge and the leather upper. In my opinion the sharp thin metal edge of the underside of the brake pedal as described herein is a dangerous and extremely problematic issue. After the recent incident, I am consumed with concern, trepidation and fear when operating the vehicle. During the excitement of the near collision, my wife made an audible gasp, and in the split second I struggled to free my shoe and foot to avoid a potentially fatal crash. I barely freed my foot and shoe in time enough to successfully bring my vehicle to a halt. My wife and I narrowly averted a life changing, potentially deadly accident.
