Which is the most well behaved motorway?

[Pints]

The meandering mind got me wondering which motorway has the most well behaved drivers.

My daily M4 commute between Swindon and Bristol is relatively pain-free.
Lane discipline is commendable and generally a pleasant enough experience. There are the occasional MLMs but, on the whole, it's certainly better than the M32 and M25.

I've not spent an enormous amount of time on other M-ways, but IME the M4 (or at least the stretch I do) is more relaxing than those I have travelled.

So over to you, which motorway of Great Britain has the most well behaved drivers?

Surely to be able to form an opinion, you'd have to regularly drive on EVERY motorway, which is pretty impossible.

Which is why I'm throwing this out to the PH massive. Collectively, our knowledge and opinion knows no limits!

Regardless, the M69 is delimited isn't it?

Have I missed something?

Me too. Eh?

Not strictly true. Originally it was delimited, but following local government consultation in early 2005 the maximum permitted speed was reduced to 150mph (although V8's are exempt)

Sauce?
