A470 between Heads of the Valleys and Cardiff.
It’s a two lane battle ground jammed with broken heroes on a last chance power drive every morning and every evening as the people of the South Wales Valleys head into Cardiff for work.
Lane 1 is full of plodders doing 40 (when it isn’t at a standstill which is often is) lane 2 is full of lunatics doing 80 2m from the car in front with another 2m behind.
Women doing their hair and Lads brushing their teeth in lane 2 is a fairly common sight, no quarter is given or received, ever, couple all that with lots of roundabouts with 3 methods of use: the correct way as dictated by signs, the correct way as dictated by the Highway Code (aka the wrong way) and the “whichever queue is shortest and cut in at speed at the last moment” way – this means they jammed a lot, which means the queue stretches well into lane 1, when the plodders reach it, they’ll swing out into lane 2 with little warning, a 40mph speed difference and no space – rarely a great mix.
It sort of works in Summer (I’m going the other way thank god) but in a few weeks the worst day of the year for driving will happen – I’ll be dark for the first time at rush hour and accidents will happen, mostly as the valley dwellers will find out for the fist time in 6 month of their headlights work, many won’t. If it’s raining that day (50-50 chance in Wales in autumn) it will be charnage. For the rest of the GMT their will be accidents more mornings and evenings than not.
