Topic: You say it's impossible to avoid contact?
You see this car? The 1967 Fury III's original shipping weight was 3,615 pounds. It was by far the biggest car on the track at the Goin' For Broken race. It has torsion bar front suspension, leaf spring rear suspension, a solid rear axle, and a hood the size of a tennis court (well, if it had a hood, at any rate). It was considered big and unwieldy even in its own time. And yet... this freakin' dreadnaught did not get black-flagged even once all weekend.
How? Well, motivation was part of it; the Size Matters guys have deeply held religious beliefs that preclude the application of Fiat branding on a Mopar product... which is exactly what was going to happen to them if they showed up in the Penalty Box (we Lemons officials are aggressively atheist when it comes to the whole "sacred marque" business, be it Plymouth or Ferrari).
But the main reason they didn't hit anybody and/or go pinwheeling off into the tumbleweeds is that they didn't take chances. They didn't let themselves get put into a position where some racing noob with delusions of grandeur and/or a 79-alarm emergency clanging in his or her head could force them into a metal-on-metal situation. Even if it meant that they had to wait an extra 90 seconds to pass some parts-shedding sluggard, they didn't slice their margins of error thinner than Neon sheet metal.
So, all you racers who screamed at the Lemons Supreme Court about how contact was "unavoidable," just contemplate the USS Size Matters next time you see it drop anchor near you.
