I walking home yesterday afternoon having been out for a stroll and just happened to have a camera in my hand when I was passed twice by a couple of youngsters driving back and forth through the village; I'd estimate they were exceding the 30mph speed limit by a factor of two.
Hot Car, or Hot Head? You decide.

so dangerous...they are just oblivious to people and life outside of their little bubble......

by a factor of 2 does that mean twice the speed? blimey....that's bad...
