I don't understand the SCORE

In the Gen3, typically the friction brakes are not used down to 15-20km/k when the CHG are is not full and you press more. Gen4 supposedly should be the same...
But a few things are not really the same in this HSD implementation.

 

I don't know because it was a mix of highway at 50-60mph, the aforementioned panic highway piece at 70-ish mph, rural secondary roads, and some urban streets.

Italy is part of the EU, right? For the past 10 years I have gone to Turin once or twice a year, which involves travel on the autostrada between Turin and Milan, and elsewhere. Thanks to a camera-and-computer network, there is little speeding on the autostrada: if you get from camera A to camera B faster than you should, a ticket is mailed to you. The limit for cars is either 110 or 130kph, though not all cars go that fast; for trucks or cars with trailers it is 80kph, which is rigidly adhered to.

I would think one could drive at any speed between that of the trucks and the max for cars without issues. Years ago I drove from Stockholm to Freiburg, Germany and back in a Fiat 850 sedan. We were forced to mingle with the trucks because it would burn valves if it was pushed over 100kph (in fact despite our care we had to stop for a valve job on the way home). Apart from being extremely watchful before pulling out of the right lane, traffic was not a problem.

 

Yes, Italy is part of the EU.

In Italy they are introducing more and more the "Tutor", that you mentioned, which not only will fine you if at check-points you go faster than the speed limit (typically 130km/h), but also if your average between 2 check points is higher than the speed limit. This has finally give some peace and quiet on the highways which to many people thought were F1 racing tracks, tailgating those who were overtaking at the speed limit is slightly above and other typical situations.

The issue in Italy though is that too many people don't keep to the most free right lane, considering it for trucks/lorries (even if there are none) or for "losers" - hence the occupy middle lanes, going maybe 100km/h. They are the ones that cause the most grief as you are not allowed to over take them on empty lanes to their right, but only to the left. Not keeping the most free right lane is becoming more often also the issue here in Germany. Drivers simply want to stay left, considering right lanes not "nice" for whatever reason.

What it is allowed though, is to be on the right most lane, and "overtake" to the right, if you maintain the same speed and don't change into it, to over take somebody. Which means, if you are travelling at 130km/h and somebody in the lane left to yours is driving at 100km/h, you don't need to go 2 lanes left to overtake him. Problems is that most don't know this rule and are taking by surprise if you approach them at a relative speed of 30km/h from the right.

Truth is that most think of themselves only and don't understand they are sharing the roads with others.
In Germany several sections of the Autobahns don't have a speed limit, but being more and more congested, most sections have all sorts of limit - fixed or variable (computer controlled). Moreover the advised speed limit is 120km/h (or 130km/h, I don't remember now) and if you are any faster than that, you are immediately liable in any accident you are involved, even if you were totally right and had no fault.
Essentially, drive fast at your own risk.

I find driving in the USA in general more relaxing because the highways/freeways have more lanes, are more flat/straight, you can overtake on both sides and in general people drive more or less all at the same speed. There is the occasional "rogue" driver zig-zagging around not thinking that he will be caught easily, but otherwise everything is quite fluid, at least my experience.
The only thing I found weird, are the sometimes very short access lanes, where you really need to kick down to get up to speed as nobody will change to the left lane to let you in (which is instead required in the EU, to let new cars join in, unless you brake). So you need to reach a high speed, extremely quickly.

With the Tutor in Italy the situation is more relaxing in general and more like the USA and I think the accident rate has decreased enormously (and drivers have finally discovered what the CC is... ). This is way the authorities and Autostrada licensees are expanding the "Tutor" sections more and more. I wish they had the same in Germany. Driving in Germany is mostly stressful.

 

When I do that it still doesn't go up. It seems I need to fill it just a bit and brake very long to get to 4/5 spots. Gliding and even acceleration are always 4 or even 5 bars.

I am currently keeping the HSI in the right MFD/screen because it shows when the car is in EV mode, the HUD one doesn't and in that case the only way is to look for the instantaneous fuel consumption in the left odometer/MFD screen.
I think I will soon put some other screen in the right one as you proposed, and like I did in Gen3, the HUD will soon show just the speed. The best way to increase MPG is to lock for the traffic ahead and drive as smoothly as possible. In the left MFD screen I will either keep the fuel consumption or the HSI bar, and likely not the battery level. I don't know - we will see what I will reckon to be most useful.

I had to change the brake discs and pads at 80.000km because of salt that made them rust before hand. I am still not sure if they played on me to simply change them well before hand or not. But if you drive 180km/h on the autobahn at times, and they tell you they are rusty (and I could see that myself) and they brake less than optimally, I do change them...

Some countries seem to have enlightened leaders and managers. I should maybe move to Canada.
In Germany there are only signs that tell you to buckle up and slow down (because Jimmy is waiting home for you; actually your wife and daughter, not son).

And in Italy they write more about not talking on the phone, and promotions for highway payment transponders and crap like that. While in the meantime drivers merrily drive underneath such signs talking on the phone, and counting the coins to pay cash at the exit (there is toll on all highways in italy - you can pay for free with credit cards, but that is too far fetched of a concept for my fellow nationals and requires a bank account which would expose too much the taxes they are not paying; and I could add 2-3 more other reasons).

Writing to "keep right", not a blip anywhere in both countries.

 

In my brief experience, coasting before braking appears to play a part in netting 5 bars. The longer the better. Energy saved by coasting will always be greater than regenerative braking can produce.

 

Did you always have the sheep skin on the bench?
