Definitely not the kind of thing to try on public roads, there will always be someone who does though :s
I've had the back end out on track plenty of times, hell most of the time on purpose just to get it to turn in but I wouldnt say they spin easy if anything the opposite.
whats the big deal, if you know how to do it and you know where to do it then I see no reason why you shouldnt, of course I am not talking about long slides like the ones in the vid but you can still have some fun with little oversteer here and there
