I was wrong about not including thinking time but I remain convinced
that retardation rates much in excess of 1 g are outside the realms of
reality for normal road cars even on the best of road surfaces.

If you plug 0.1 secs back into that sum I did that means you only lose
3.1m in thinking time. That reduces the deceleration to 0.94g

(might be worth pointing out that some of the more "performance" cars
they tested would stop shorter - 49m being the best IIRC)
