Interesting thread. I just figured the posi argument was just going to be "in favor of".
I am in this camp but some interesting posts for the "none posi" side also.

Over 50 Years ago when dumb kids used to race while cruising I was with a fella in a V8 powered Rambler Rebel, without posi. It was raining and he got into a stop light race with a VW bug.
He didn't let up on the gas, to possible gain some traction, all the while one tire spun and one didn't. The VW beetle beat us to the next light.
I still laugh about that one.
Cheers.

Cruise control + wet slippery roads + redline does not compute here either.
Bad idea. Any modern car, with traction control, would shut off the cruise control if the driver tried something this silly.
