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.

I had a similar experience two nights ago where the car in front of me just slowed down for no reason before joining. I was checking my shoulder and only realised when it was too late.

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.

Autonomous driving is an amazing idea, we just don't have good-enough implementations yet.

Yes, but you can go at 70mph (in uk at least) so you don't need to speed to overtake. A speed limiter would make no difference in this situation.

I'm in the UK. It wasn't a comment on the limiter as such, rather pointing out to the above poster that going under the speed limit can be very dangerous too.

Many places have a minimum speed as well for highways, so that would be illegal. It's probably less enforced than the above-limit infraction though.

There is no standard minimum speed limit on motorways in the UK unless indicated by a blue circular sign, which can apply to any road. These are rare. Motorbikes under a certain power limit, disabled vehicles, bicycles and horses are also not allowed on motorways.

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.
