And yes with enough power a cinder block will fly but that becomes more a function of thrust to weight rather than aerodynamic lift if my thinking is correct.

Yeah,lift is like the plague,to be avoided at all cost.The bummer is,that for human packaging,cars have ended up with shapes,which because of the way they divert flow over,around,and under the car,low pressure areas arise which induce lift,which increase geometrically with speed.------ In the 1970s-80s,Dr.Alberto Morelli developed a car form of low drag and zero lift.So since then,it hasn't been necessary to have lift,although if you don't respect Morelli's work,well then you're stuck with lift.-------- The palliative has been spoilers,front and rear.They would have made a big difference on the LTD.---------- And yes,the cinder block example is thrust-to-weight.You can do it,but today most would argue the folly of it.Some carmakers not only went with flying barn doors,they've gone ahead and put the barn on wheels.You may have seen a few of 'em.Kinda like a cinder block when you think about it.
