Edit: For some reason, YouTube has decided to remove this video. I'll keep an eye out and see if I can find it somewhere else. Shame. It was one of the best pieces of public education I'd seen for a very long time.
I've seen this clip in various different places recently, but I first spotted it on Jumblerant.
Mine must be one of the businesses where we'd rather not drum up more business, and this is one way of trying to reduce not only the workload, but the heartache that comes with it.
Learn from it.
Warning - this isn't a child-friendly video.
Just in case the video link doesn't work - here's where it can be found: http://tinyurl.com/carcrashtv
Please, please, stay safe out there.
I'd be happy not to have your custom.
