i have a suggestion. If everyone (brian etc) if so worried about these damn bollards, how about the retired and bored among you go and stand next to the entrance slip road, with high visiability vests on and stop offending vehicles from hitting the bollards.
Worthwhile i think...no more injuries, no more smashed cars, no more expensive repair bills for the tax payer. its perfectly legal, and you would actually achieve something rather then just bickering amongst yourselves over whether one can see signs or not. Does it actually acheive anything? (Having said all that, the drivers would still ignore you anyway, then you will learn why people keep hitting them. Most drivers are unattentive idiots)
Take action, don't just gas about it.
Even better - couldn't Threep run a book? |
