These things have limited high speed stability anyway due to the physics."

Probably cornering at speed."

All the electronics in the world won't defeat the laws of physics (the dynamics of rectilinear motion).

"Armstrong Sid

Litigation (or potential litigation) culture gone mad and every manufacturer is paranoid about anything which might happen in the hands of an idiot."

I suppose that the above answers put it in short.

My late father, long gone, warned me when I got my first motorbike, "Be careful, you can avoid fools but not b***** fools".

Although, please can ijws15 initiate me into the meaning of ‘dynamics of rectilinear motion’.

Once, when I was working with Hyundai in Seoul, I spent a pleasant half hour coaching a Korean engineer in the pronunciation of words containing L and R. I used rectilinear as a test word. Other races who mix up L and R are Thais and Zambians. A Thai engineer once told me that he wanted some Denso tape to prevent his Loof Reeking.

Sofa Spud,

Doubt the families of the 53 dead toyota drivers would agree with you!
