If there was no speed limit on the motorway, what speed would you do?

Just 63 litres.

I guess that involves a lot of engine running whilst car stationary/creeping forward. Certainly skews the MPG figures more than drinking a lot whilst eating up the miles.

My work / gym commute and a huge mix of dual carriageway with roundabouts with traffic lights, motorway and driving in central London.

It entirely depends on the circumstances.  When I last lived in the UK my commute to & from work  was ~85% dual carriageway / motorway (A41 & M25), and traffic speeds there ranged from walking pace to 100mph plus for short bursts - it was entirely down to the conditions at any particular moment.  The 40 mile journey could take as little as 37 minutes, or as long as 3 hours.  Most journeys were around the 45-50 minute mark, meaning that the average speed on the motorway / dual carriageway was around 70mph, as it should be.

If there were no speed limit and the road was dry and clear I would definitely stick my foot on the floor and see just how fast my GTi will actually go but I can't imagine doing it for long for reasons of economy and stress.

I generally do 70mph-ish as indicated by the GPS.  At that speed I'm usually overtaking but occasionally overtaken which I'm happy with and I'm not burning too much fuel or risking points.

My only experience of unrestricted autobahn was driving overnight to a wedding in Germany.  We were taking turns, the road was empty and it was someone else's company car so keeping it around 100mph most of the way.  As others have mentioned it takes a lot of concentration to cruise at that speed for long periods.  I had a minor moment coming up on some temporary roadworks and had to brake a lot harder than I would have liked when I realised we were all going into one lane.  No harm done other than waking the passengers
My neighbour wiped out on his motorbike on the way to the Nurburgring when a deer jumped over the barrier and tried to cross the road.  Not everything is within your control no matter how good a driver you are.

Well sighted, empty road in excellent condition and perfect weather conditions? 180 , or 155 depending on which car I was driving.

Because that rarely if ever exists in the UK? Probably a comfortable cruise at up to 110mph in "normal" conditions.

80mph, as the poll says it's what the average is now and the conditions would obviously be the same as they are now.

I chose 70mph, not because I don't like change, because the roads are full of morons that can't handle the rules regardless of speed.
How are these bulbs supposed to send texts, put make up on and let insta followers know what size stool they passed this morning while observing any kind of speed "limit"? And don't get me started on Bimmer and Aowdy drivers......

As said earlier, lane discipline on the autobahns tends to be much better, allowing for the higher speeds on the derestricted sections.  I also think that, because there is a logic behind the German limits, and that's generally pretty clear to see, where there are limits on the autobahns, those limits are respected more.  I've also felt when driving in Germany that the HGV's spend much less time in overtaking lanes, which makes it much more possible to have higher speeds in those overtaking lanes.  Nothing worse than someone having to be in lane 3 at 65mph, because some mobile chicane is overtaking another at 56.1mph compared to 55.9mph.

I also think the French system of 130kph in dry conditions, 120kph (I think from memory) in wet conditions, makes sense.

My speed depends on the road, how busy it is, and the weather conditions.  I tend to limit about 80mph now, as I do my best to keep points off of my licence. However if joining the M25 of a morning, I would be grateful to be doing 40mph!

France is 110kph in the wet.
