A rigid bollard will break bones or cause death, as you’ve pointed out before with the deaths caused by gates on trails. Flex bollards may cause you to fall if you clip one, but that’s it. You should be riding slowly on those trails anyway, so a tumble will result in minor injuries only. Also, a rigid bollard will not withistand the impact of a car either. It will also not give if you clip it with your handlebars, so it will most certainly cause you to bail. If it’s a flex bollard, you clip it and just keep on going.
I think we could all agree the best solution from the onset would have been a raised curb separation.
I am happy that I don't have the experience of hitting either a steel or a flex bollard, so I cannot say with certainty, I'm not willing to test it either way.
That being said, the experience for cars is far different, the flex bollard is intended to be driven over without damaging the vehicle, steel bollards not so, they will damage a car to some degree, even if they inevitably, get knocked down. Of course, some steel bollards can stop vehicles: https://www.youtube.com/watch?v=GIywj53l-8E but that's probably overkill for uptown .
Regardless, the difference isn't really enough to care about I don't think. For all I know it's a maintenance issue.
@Spokes and Canard I totally agree that the best solution would have been a curb, I cannot comprehend the regional engineers obsession with roll curbs. Their arguments for them, barely hold in uptown, and have zero logic in other locations where they are still insisting on roll curbs. It would have been the same cost for roll curbs vs. barrier curbs. There is some staff member, at some high level who is insisting on this...what motivation, I cannot guess.
@Panamaniac They said during the presentation that the exact positioning was still unclear, they said they'd like to attach them to the curb portion at the edge where the curb is level, but were unsure if this would be feasible, as Canard points out, attaching to the rolled portion would be hard.
