In my Porsche while entering the highway on a cloverleaf curve I took the entry ramp extra fast to shake a Fox body Mustang off my tail.

Much to my amazement he stuck to me like glue.

I got a better view of the car and driver as he passed me on the highway.

He had some serious mod's to the car and knew how to drive.

Color me impressed.

Decades earlier a Ford Escort driven by an aggressive young woman (I swear she was going to hit me a couple of times) tried to follow me into a sweeping curve at 15 mile (Maple) and Telegraph, a curve I drove every day into work at "speed" and at my Diesel Golf's limits.

Well, I swept though the turn as she tried to mimic me.

It didn't end well.

She jumped the curb and totally messed up her front end.

I was laughing, school of hard knocks calling.

Back on topic...............seems aircraft have other issues to contend with.

What is the relation between drag and weight?

Say we compare two A320s, the one heavier by a factor of 1.3. Of course the heavier one will fly with a higher angle of attack, because it needs more lift.
I suppose hull shape and ship weight will have additional factors to consider as well.

More weight on a road vehicle could mean more tire deformation, more contact area, more rolling resistance.

Ever see an overloaded pickup truck?

Nose up and tail dragging would increase Cd one would think (angle of attack).
