I would guess one in 5.
As for the street racing. When I had my eclipse I'd head out to the races here in the bay area. Theoretically I raced once and only once to another stock civic. At the place where the races were, it was safe as far as I could tell. Everyone parked in the parking lots of a industrial street, everyone was out of their cars and behind the starting line in case someone got a little frisky with the steering wheel. Just in case, the people lined up would flash their high beams several times and we had someone at the other end with a radio who would make sure the street was clear. Had the people been stupid and tried to do donuts or race without the lights on, etc., I wouldn't have gone back. This was very controlled, very aware, very safe environment. This isn't your stereotypical scene, but it was something to pass the time and it's only 5 minutes from where I used to live. I have to drive 2+ hours to the nearest track (Infineon/Sears Point). I can drive 3 hours and hit up thunder hill or 5 hours to Buttonwillow down south. It was more of a convenience thing then a rebellion thing. I've always been safe and always will be safe, that's why I want the vert. I won't have every ricer doing the flyby trying to get me to race, I'll have a beautiful car and if I feel the need to show a ricer what acceleration really is while on the freeway, it'll be a quick 5-10 second noise pedal and then I'll slow down again (room permitting of course
)
Just my opinion on street racing. I agree with the drive smart, not necessarily slow posts as well. And also, if you can afford it, I HIGHLY HIGHLY HIGHLY recommend going to a driving school such as Skip Barber, Bondurant, Russel, etc. I was in the 2 day driving class and it was the best education I've ever gotten. Defensive driving, offensive driving (track use only) and seat time practicing all these in a variety of vehicles proved to be INVALUABLE. I can now comfortably and calmly react to emergency lane changes, stopping a spin, holding a slide (drift), and braking better than ABS. I could go on for hours about it but can't afford to go back. =(
PS. I went to the street races in AZ when I was going to school there. first time I went out to DV and someone shot a few rounds at the "ghetto bird" as they called it. That was it for me. I went to Firebird raceway a few times to watch some races after that but nothing illegal down there.
