The tosser’s lane on the M90 northwards towards the Queensferry Crossing. It’s clearly a rat run for impatient drivers approaching the bridge at busy periods. The lane is ostensibly for traffic going west before the Forth or going into Queensferry itself. It’s irritating watching them while you’re sitting in the mainstream lanes, but worse than that are the frequent and dangerous antics of the more ‘erratic’ idiots. The lane seems to be fairly empty during normal times.
