I remember, back in the day I saw a car test that quoted drag coefficients for the SA cars with and without the lights up. I don't have the best memory, but it seems that it was something like .29 lights down and .34 lights up. Does that even sound right?

That's a very informative video and a good explanation for why cars evolve toward better efficiency and safety and all start to look the same.

However it does't take into account the most important thing about 1st gen head lights: They are beautiful, up or down.

That guy speaks using "uptalk". Sounds like he's always asking a question. It's distracting and unpleasant. Takes me out of the discussion. Makes him sound like he's asking permission instead of providing facts. Hard to take anyone who uses uptalk seriously.

would you rather him sounding like James Earl Jones, or Barack Obama where the last syllable is low resonance and everything no matter how retarded sounds profound? or how about that buzzing sound that yankee football announcers on NBC make. UK/Irish/Scottish accents really "get my knickers in a bunch, makes me want to tuffle" . WTF?

.29 and .34 sounds like FC numbers, the FB is more like .32? and .36? i guess i could look, but facts are so dry
