2. If you're following a slow driver. By definition they will be going below the speed limit. You yourself say people don't know how to handle a car at 80mph. Why then allow them to reach that speed to overtake?.
That doesn't mean it's safe. I had the terror of joining the motorway behind a car doing 30mph last night. It kept that speed once we miraculously made it onto the lane. It was an absolute menace.
It was either rear end him or join. My front wheel came off the ground in my frantic attempt to gain the speed of the car just behind me. Fun times.
Maybe autonomous driving really is a good idea.
There is however the offence of unnecessary obstruction of traffic, which any bellend doing 30mph on a motorway might find it quite possible to be found guilty of.
Precisely.
