that depends on Your assessment of speed. I naturally assumed that breaking the speed limit was speeding. in your case, you obviously think that you never have. now that depends on wether or not you drive. All motorists break the speed limit, even if it 1mph over that is still breaking it. do you stay within the speed limit? have you ever done an advanced driving course? police driving course, or a defensive driving course? I don't know you personally, so I assume not, as most drivers never take more than their driving test. So i stand by my assessment, that all drivers speed! even if only by 1mph that is still speeding, by definition.
and fyi, yes, advanced driving, and defensive driving courses. I have also done the police speed awareness course, as an assessor, so I have a little insight. and i emphasize the little!
ps i have been over taken on a road while doing 30 (speed limit on road) by a gentleman on his push bike, but he was not breaking the law. go figure that one.
