What does it mean to be 'loose' in NASCAR?

Answer 1

>In Nascar "loose" means that the driver has to control the wheel more than when >it is tight. When it is tight the driver barely has to turn the wheel to get it to go >around the curve, as when it is loose you have to turn it more.

Incorrect. Loose means the car oversteers, i.e., the car turns more than you expect and/or the rear end wants to come around so you have to countersteer. Tight means the car understeers, i.e., the front end doesn't want to turn or it turns less than you would expect with the angle you've turned the wheel so you have to steer more into the turn.

Answer 2

They refer to the wheels in the race car when the car slides out of a turn, mainly in turn 4 because of its higher banking.
