Thats happened 100yrds up the road from where I work. Apparently the police have worked out they were doing ~70mph when they clipped the kerb. I think theres a lesson to be learnt there.
Do you work at the Shell Garage or the Willy Wicket pub?
I'd say they must have been doing well over 100mph or the driver was so smashed on drink and drugs that he didn't brake! I have seen my mate spin his MR2 in the wet at about 40 and it didn't even hit the curb on the outside of the roundabout. To skid that distance and hit a wall so hard as to kill all three occupants they must have been near the cars absolute top speed in a 30 zone!
Still thats what happens if you put 3 dumb ass 17 year old lads in a car! Of course this will now result in a speed camera being installed and decent motorists getting nicked for doing 34mph when that had nothing to do with the deaths.
