In the Fort Lauderdale recent crash the NTSB said the car was going 116mph prior to the crash that killed two teams, when it hit two walls and burst into flames. I live near that area and have driven it 100s of times, the area is rated for 25-30 mph and before that is resort hotels beach area then turns into a residential area, the walls that are their are to block the A1A area and give the homes some privacy . RIP so sad and senseless way to die.
