Arguing with my dad who was the passenger!
3 lane motorway. I was in the left lane, cruising around 70 as no one in front. Came up to a car in the centre lane doing around 50mph. The right lane was running fast, I’d guess over 70.
I assessed the safest thing to do was carry on being very vigilant and slow a little bit and steadily pass the slow car in my lane at around 60. The alternative was get behind it then attempt to accelerate into the fast flowing right lane, accelerating in between higher powered cars from a much lower speed. I’d been forced to slow a bit on approach already, there was no obvious gap in the right lane which everyone as crowding into on approach from the centre lane. The middle car clearly wasn’t shifting, the left lane ahead of me was very clear. The road wasn’t otherwise particularly busy, the right lane was just busy because of this car.
I was very aware, ultimately had a hard shoulder for emergency and I was watching the car well for any sign of switching lane.
iabu- you should have crossed back and forth over two lanes, as it’s always the passing lane
Ianbu- this was the safest way of dealing with the hazard.
