I would guess running over a steel bottle would be similar to the many times I've run over my plastic bottles: bottle skitters away from leading edge of wheel, zips across road, ends up in muddy ditch.... and I go scurrying after it!
When I took a skills class one of the things we did was try running over bottles. It was great fun, and never ONCE was I able to make my bike actually go OVER a bottle, they always skittered away. (just like my own bottles in the wild)
Someone willing to risk the finish on their steel bottle and tell us how they do being run over?
