This sounds like riding an Indian Chief Motorcycle. With a
right handed stick shift and right handed hand brake you
frequently had to reach across with your left hand to apply
the brake while shifting. With the Indian you could lay it
over until the floorboards scraped (We didn't have foot
pegs.) then crank the throttle and it would straighten right
back up again. Like riding a giant gyroscope. Of course you
had to actually have some space in front of you when doing
this.
