"This worked for me, but no guarantees. I found the split axis detection a
bit iffy. What usually happened is that the Accelerator would be detcted on
"Accelerator -" and the brake on "Accelerator +" (as opposed to Combined
Pedals +- for non-split axis). This may sound OK, but when you let go of the
accelerator, I was automatically braking.
Evetually, I got it to work with "Accelerator -" on throttle and "Brake -"
on brake. Here's what I did.
Press both brake and Accelerator then clicked Brake. After each attempted I
lifted off on the Accelerator a tad and clicked again. I repeated this (in
very quick succession - In other words, repeated clicking whilst easing of
on the accelerator) until it detected "Brake -" and viola. The Accelerator
is detected as per usual. It was always the Brake I had trouble with.
Hope this helps, it sure improves the driving."
