This thread's a bit like watching, "Australia's Funniest Home Videos" where some poor bloke get's his old fella whacked and we all have a giggle
But it is good to be reminded to keep our vehicles well maintained and what careless driving or just bad luck can result in.
To add to Aussie Mike's post, I was standing near Greg Hood's son when Greg hit the armco on pit straight. Naturally he was pretty upset as the off was a big one and Greg appeared to be initially knocked out.
