Do you know anyone who actually owns a dashboard camera? Or, as they're more commonly known, a dash cam? Because if you do, we'd like to thank you for producing videos like this one.
Recorded by a kind-hearted motorist looking out for a fellow motorway user on the Gusinobrodskoe Highway in Novosibirsk, Russia, it shows a BMW driver suffering a serious mishap in the middle of the road.
One moment he's driving along happily, the next his front left wheel has popped off and he's screeching to a halt.
Luckily for him, the inadvertent Siberian cameraman stops just beside him to help a brother out. Makes you feel warm inside, doesn't it?
Of course, it's not the first time a wheel has come of a motor vehicle at an unfortunate moment. Check out this little gallery of racecars, dragsters and motorbikes all losing a tyre when they really, really didn't want to...
