Why are people scared of the drag strip?

My oldest brother had plenty of excuses, here's some of them...........
-I have nothing to prove, i know my car would run mid 12s.
-Drag racing is too hard on the body, it flexes the car too much.
-I just put on new tires, i can't afford a new set just to run a few runs to try to be a big shot in front of you.
-My engine isn't broken in yet.
-It's too expensive to buy race gas, track fees, a helmet, and a fire suit.
-I'm not going to rev my 440 to 7 grand just to impress you.
-Why would i risk crashing the car into the wall for you?

B.T.W., his car was a '71 Challenger R/T originally a 383 with a re ringed 440, 906 heads that were lightly ported with the D.C. template kit, a 484 purple shaft cam, headers, electronic ignition, and a 6 pack intake and carbs.
It also had a column shifted 727 with stock converter and a shift kit, and an 8 3/4 3:55 sure grip with 15X7 rallye wheels and 255 60 15s on the back, all steel car, full interior, and weighed about 4,000 lbs if it weighed 1.
My guess would have been mid 14s at around 100mph if that.
If that...
