Nick,

We have a lot of the grated bridge decks here in the Northwest. A trick I learned in my wasted youth was to cross the bridge at a slight angle within my lane. If the bridge was long, I changed my angle from one side and then back to the other. This is performed in a very smooth motion! Also, leave pleanty of interval. ABS or not, stopping distances are probably twice normal.

I have witnessed numerous cars nearly spin out when their drive wheels lost traction and the vehicle took on the attitude of an out-of-control dragster... that is in the dry! Wet surfaces are even more entertaining.

This method was brought to my attention by a more experienced riding companion as I picked myself up from a motorcycle spill on one of those grated decks.

The Geo driver probably felt a similar sensation but to a lesser degree as those tires are much narrower... less contact surface to be affected?
