Heh; don't take yourselves too seriously - the patent part was a joke. I was merely inputing context to fuel a discussion on one of my observations: I've seen sharp angle turns with slick tires cause several accidents. I recovered before I fell last month, and I've just remembered not to go too fast on even moderately sharp angles. I was just inquiring as to why such techniques are labeled as "useless" and have "no advantage." Can any of you who have said so explain why? Thanks.
