SE5 Transmission Won't Downshift

[Questions]

Because some of us are disabled for one reason or another and don't have the liberty of shifting with our legs but we still want to be in the wind....

My situation exactly. I don't have the luxury of being able to use both hands or feet. Only my right hand side works. I actually love the way the SE5 shifts. I love the way the "nanny" alows u to do wicked burnouts until you back off abit and the traction control kicks in. That was a surprise for me and I am left wondering why they might have "built this in" to the design other than to allow us "automatic" (read tiptronic) riders to be hooligans once in a while. When hard on the gas this thing shifts as well as any manual I have ever ridden. I understand the value of a clutch, it allowed me to do things like in my signiture... but those days are over...
p.s. the Ferrari F430 with tip-tronic apparently uses a similar gearbox design as the SE5 but I wonder if they have problems?
