I dont think it equates to 100mph, But thats hardly the point! 
It is fustrating and not sure there is anything you can do apart from if you see orange flashing lights deploy the handbrake and quickly shank it right. Head in the opposite direction! 
yeah im sure it doesn't equate to exactly 100mph but something getting thrown out at 50mph in one direction and then hitting something coming the other way at 50mph will be 100mph minus the three feet from the dispenser and my bonnet which will prob take it to 90mph but lets not get technical as you say.
each time I get hit I say to myself I gotta watch for these motors, then a few days pass and I forget, the roads I travel on are all b roads, 60mph speed ,limit and just twist forever, usually drive at 40 or 50mph max but there is always cars behind you and the roads are so narrow that moving over aint an option and slowing down is only marginal due to others on my tail as they want to drive at 60mph +,, anyway I never see them until it is to late due to the twisting roads.
very very annoying,,,,, do you guys think the grit actually chips the car, im assuming the council have done their homework and wouldn't design them to do this but at the same time it is the council we are talking about here
has anyone been hit with it yet this year ?
