I don't understand this obsession with "70mph."
It's far more dangerous to go a couple of miles per hour over 30mph in a built-up and busy area where 30mph is the speed limit (pedestrians, cyclists, dogs, cats, vehicles stopping, turning using junctions etc.) than going 5 or 10 mph over a 70mph speed limit (on a dual carriageway or motorway).
I'm not trying to justify speeding, I'm just very cross at the number of ill-considered populist laws that are being proposed these days in the name of safety, whether it's safety from terrorists, safety from perverts or safety from anything else.
When all the traffic is traveling at the same speed in the same direction, the risk of collisions is negligible. That's why motorways can be so safe... but nowadays we have different speed limits for different vehicles on the motorway so lorries jockey for position at ~50mph, old grannies do 45 in any lane they please and the PHBs and salesmen do 100+ in their Mercs and BMWs (also in any lane they feel like, changing without warning, without looking and without signalling).
My driving is the best in the world. Everyone else is rubbish.
One day I will rule the world!!!! Be afraid all ye who read this warning.... Muhahhaha!!!!!!
