Sorry for the "late" response.
The point raised about there being numerous tracks, mostly back in the day, that were less than safe is very true. Technically speaking, NHRA once had a rule for tracks that stated the spectators had to be a minimum specific distance from the racing surface. But when a track they wanted on their list became available, that "rule" was often ignored.
Down through the years there have probably been dozens of outlaw tracks that weren't sanctioned by any legitimate racing organization. There were also others that had recognized sanctioning body signage that weren't really sanctioned. Someone painted a sign to make participants and fans believe they were legit when they weren't.
I'm not trying to badmouth anyone's facility, but places like Summerduck Dragway in Virginia was no wider than a suburban driveway -- and not much longer, either, yet famous doorslammer runners like Nicholson and Sox match raced there all the time. Capital Raceway had a steep tree-covered hill at the end of the shut-off area (what there was of it!). U.S. 30 Dragstrip in Gary, IN had a railroad tie wall at the end. Oswego Drag Raceway was an elevated track on a berm with almost no quardrails of any kind. Heck, the old Beeline Dragstrip outside of Phoenix had single rail Armco guardrails located so far off the racing surface that an errant car would have built up more than enough speed to make it into the spectator stands had someone gotten loose. And the photographers stood IN FRONT of, not BEHIND those guardrails!
I went to Puyallup Raceway (did I get that right) in Washington years ago for a Funny Car show with the late Steve Evans and Bill Doner. I asked them about a photo pass and Evans said, "Hell, just go on out there. No one's gong to stop you."
The crowd was almost standing on the racing surface. "Who sanctions this place?" I asked.
"OHRA," replied Evans.
"What the hell is that?"
"Our Hot Rod Association!"
When you really think about it, and compare some of those old places to venues like The Strip at Las Vegas Motor Speedway, or Bristol, or the Motorplex, or Route 66 Raceway, or Norwalk, it's a wonder everyone wasn't killed long ago.
As to the ambulance issue, one of the responses was dead on (an unfortunate word choice, that!). I witnessed a fatal Top Fuel crash at an Illinois track where the ambulance was literally a relic from the late 40s (this incident took place in the late 60s). Not only did it take them almost 20 minutes to get it going, the "attendant" was just some kid working at the track. Had the driver still been alive there was absolutely no way he would have received life-saving assistance. The coroner had to be called before the car and body could be removed from the racing surface.
Safety is an on-going issue that can never be ignored. When I was lucky enough to do some driving in association with the Frank Hawley Drag Racing School I always wore far more gear than was required for Super Comp. Everything from full Nomex underwear to a suit that was "approved" for much faster classes to an eye-hole Belaclava underneath a full face Bell helmet. Even though those cars don't run 300 MPH, they can crash (Just ask young Ms. B. Force about that), and gasoline does burn.
The "It'll-never-happen-to-me" theory doesn't work in racing, and the list of injured drivers that DRAW assists every year attests to that.
Two years ago I watched the winning Super Comp driver at a POWERade race climb out of his car at the top end -- with no socks on! I don't know where the staging lane people werre when the guy climbed into his car, but what, if anything, was the guy thinking? "It'll-never-happen-to-me," probably.
Some years ago a Comp racer sued NHRA after getting burned because he didn't have his firesuit bottoms on. Who's at fault in that situation, NHRA or the idiot who climbed behind the wheel?
You know my answer.
Don't just make sure about yourself. Keep an eye ouut for what the other people are, or in this case aren't doing. It could save your life.
