Good video for reminding us to use extra care.
I never have, but I almost have, a few times, so I'm hoping that counts as "has" so in the future I won't
.
My home runway is 40 feet between the markers, and my taildragger's wingtip floats have a 20 foot span, so it keeps me honest. I think it's easier to keep it straight on a narrower runway, as you have less room for error. Keeping it straight, and right down the middle of the runway is the best way to prevent a groundloop.
The more likely a plane is to nose over, the less likely to easily groundloop.
(I tried to link a video clip of me doing it in my 150, on the ice, but the link did not take...)
If you really really try, you can make a nosewheel plane groundloop too....
