Well, I'm sure that driver was expecting to find a crowd of 50 people standing in the street at 3am.
This is why it's illegal to watch street racing too. Granted if the driver of the "sedan" (looks like a big ass Cadillac to me) really was driving around w/ his headlights off (I bet it was an old guy), he's just about as dumb as the street racers... but I'm not really feeling all that sorry for people that are intentionally spectators at a dangerous "motorsports" event w/o anything protecting them from the cars. You wouldn't stand on the track at Daytona to watch would you? Sounds like a good way to get yourself killed.
