Yes, a better idea would be to enforce decent lane discipline. 
Indeed.  

The argument I heard on the radio this morning that people aren't capable of controlling vehicles at 80 but are at 70 is of course, utter nonsense.  
I don't know about this, but I think we should also consider the consequence of accidents at 80 as opposed to 70.

I would imagine the difference between crashing and being pulverised at 70mph are not significantly different to crashing and being pulverised at 80mph.

I guess there's more energy to transfer at 80 than 70. Someone should work that out.

Kinetic energy increases as the square of the velocity, 0.5 x mass x velocity squared.

80 squared is 6400; 70 squared is 4900 so the impact energy is 130% at 80 mph what it would be at 70 mph. Stopping distances are also longer at higher speeds, as is the distance travelled while you are processing the fact that some wally has just cut you up horribly and you need to slam on the anchors.

At 70 mph on dry roads, the stopping distance is 315ft; at 80 it is 360 ft. Both double on wet roads.

I like driving at 80.  I won't increase to 90 if the speed limit goes up.

I still don't think that they should put the speed limit up.  There are people on the motorways driving at 50 because that is the speed that they are safe driving at.  There are other driving at 80 who aren't safe going more than 50.  70 is a reasonable speed, and I see no reason why it should be increased so that people can get to Birmingham 10 minutes quicker.

Unless you're a lorry you shouldn't be on the motorway if you're only going to go 50 mph (assuming that it's safe and there isn't a temporary speed restriction in place, of course).

That could be common sense, but British motorways don't have a minimum speed limit. The police will only pull you over for being slow if they consider it to be a danger to other road users I believe.

I don't want to get to Birmingham any earlier than I have to be there, though.

But surely its wise to maintain the capacity to leave at full speed n'est ce pas?  Grin
