Slipstreaming lorries is a skill to acquire.

Did some today. It varies with the size, type etc. of lorry. |
Usually about 6 car lengths upwards behind a lorry, close up slightly and overtake and behind the next lorry in front. Itís all about getting into the zone where he is sucking you along.
This morning, solo in rain and lots of spray and down to about 50 mph unless clearish.
As some work had not been done correctly on our caravan which resulted in travelling from Catterick to Knaresborough then back up to Catterick then back down to Knaresborough again, towing.
The return trip up to Catterick was done pushing it, the rest at a steady 57 mph or thereabouts.
Been slipstreaming lorries etc.for 35 years the changes in their size and shape makes a need to adjust what you do..
The loading of your car and caravan ( weight distribution) makes a difference and you adjust as you go.
You have to slipstream in France on the Autoroutes or you take ages to get anywhere.
In May and June there were sometimes a convoy of 5 to 20 lorries, nightmare to get passed.
These lorries are all slipstreaming and the gap between each of them is usually a car length or less and I do mean LESS.
Slipstreaming, Itís not for the faint hearted. It takes skill and nerve and alertness.
One year we were going down the motorway, heading south from Claremont F. on the A75 and a snow storm hit us. I was thankful that a bright yellow big artic came onto the m/way in front of us. I was able to follow him for 50 odd miles in very bad conditions, how he managed I do not know but I think it was the design of the front of the lorry maybe pushed the snow out of the way or maybe he was a nutter wanting to get home.
Today the worst driving was cars, middle lane hoggers driving with a 2 car gap or less, travelling at 65 mph.
On 5 or more occasions I wished to overtake lorries and indicated that I am going to move out to pass. Cars in the middle lane just take no notice and just stick in the middle lane regardless.
Thank goodness with all the towing that I have done this year ( 3,500 miles so far) I can almost read drivers like a book, however you always get a few idiots about.
I am not as good a driver as I used to be before 2020 and was far better in the 1980 to 2000. So now I take much more care probably too much.
On the return trip up to Catterick I was pushing it as had to be back In Knaresborough before 6 pm and didnít know how long the repairs would take.
I found that the way the car and caravan was loaded and with the road clearish of traffic the outfit was very very stable at 70 mph for short bursts to clear traffic.
Most of the time I am a stickler for the speed limit As I prefer driving at about 55 - 60 mph as best for fuel consumption on m/way.
The difference between this caravan and our old as regards towing is quite marked, new far better.
Today reminded me of the lack of driving ability of some drivers, a bit shocking to say least.
