Um, *everyone* is supposed to slow down to the speed limit and unless you know there's a speedo under-read you shouldn't be relying on one. No-one else should be going above 50kmh so 10kmh slower would be a 20% under-read. Would you also rather they didn't speed up between 50 limits? Sometimes probably yes but if there's a line of traffic that would be worse.

I know what you mean but sometimes you just have to relax a bit. These people simply reduce your enjoyment of the drive. The actual time delay is usually insignificant. If you perform a dangerous over-take out of frustration then that's entirely on you.

You must be a very important person if delays caused by people driving at the speed limit (as indicated on their vehicle instruments) affects your day so much.

How about leaving the house a couple of minutes before so you don't get so stressed about it?

Talk about first world problems...

As someone mentioned before, a lot of times someone driving below the limit is not out of caution, it's because that driver is distracted with the phone, with a passenger, with the radio, eating, smoking.....anything not related to putting attention to the road.

You're right, it's a 1st world problem. Where I come from the deaths per distance traveled are 10 times compared to here, and no one cares, it's not a problem at all.

But then they wouldn't be diligently slowing down to an indicated 50kmh for the posted 50kmh speed limit would they? This was your complaint.

I specifically replied to the portion of Ace1's post where he suggested that people shouldn't be driving at the speed limit as indicated by their vehicle's speedometer, which would seem to be a pretty sensible thing to do) but above that (he mentioned 10Km/h) so as not to inconvenience other drivers.

There was no mention of radios or eating etc in his post or my reply.

First off, I'm not talking about inconvenience, but behaviour that can cause others to need to take avoiding action, and secondly I'm referring to those who brake suddenly, and by more than is necessary, when they get to the speed limit sign.

The problem they can cause is due to their unexpected behaviour, for example when a following car has taken their foot off the gas to slowly reduce speed, expecting to drop to an indicated 55 or so once they've got into the 50 zone, but then suddenly find themselves too close behind the braker who's just dropped 30kph in the space of a few metres. It's not about the speed they're doing, or wanting to do, so mush as the sudden action they take that can cause a trail of cars behind to all have to brake quite sharply.

As for speedo underread, it's pretty much guaranteed than any car on its standard wheel and tyre size will overread by 7-8%, so perfectly acceptable to drive at an indicated 55. Yes, there may be others who feel that 60+ is an appropriate speed, but I'm not talking about them (nor condoning it).

My cruise set at 55km/h just netted me a 40CHF fine, clocked at 54-3 tolerance giving me a speed demon worthy 51 km/h. I will now be setting cruise to 54... I know the cruise isn't always spot on and can exceed itself by a indicated km/h, but It's a cheap lesson to be a little more conservative.

I think this is a bit outdated based on the older inaccurate spinning magnet speedos.

The modern digital ones are much more accurate - the last two cars I've had were spot on compared to a GPS measurement.

You're the exception(s) then, not the rule. Manufacturers still specifically build-in an overread to ensure the don't overread once the tyres are worn. One of our cars can show via a diagnostic setting the actual speed it's getting from the sensors, which is indeed around 7% lower than the speedo, i.e. they've digitally added the extra. Another one can show a digital readout on the dash, which is also around 7% higher than real (on the standard tyres, the summer set, which were an OEM option, get it spot on).

I guess you missed the point it was POLICE car that advised to drive faster as I may be causing risk to other users of the road. Please check the driving law of local country for yourself .

What I was also saying that speed limit can't be higher than what is allowed by visibility . In conditions like fog etc - it's driver to adjust speed to the conditions however speed limit of 50 means there is conditions that permit one to drive 50kmh. Driving slower is OK - however if you believe you cant drive 50 in given place ever due to the visibility there is than two things - either driver's vision issues or wrong speed limit is wrong.

it's not uncommon to see trees and other stuff grow over the corner of the house to block the view - and every home owner gets snail mail with reuquest to cut trees etc at specific hight and distance from the street - that may be the case of the OP driving some places - and Police is there so get an look into it (as well as to send OP for vision-check in case they believe it may be an issue).

Happened to me as well a few months ago. Clear night, no fog, was driving with 40 km/h on a 60 km/h road, with one lane per direction and no possibility of overtaking. Got stopped by the police car behind me to be asked... "Warum fahren Sie so langsam?"

No papers checked, just got off with a recommendation to drive next time with "genug Geschwindigkeit." Although I was aware of the StVG Ar. 26, I never thought this was a thing in CH.

I believe he failed because he decided to drive it rather than riding it

FTFY.

Only in English speaking countries, which CH isn't.

you can check this with phone's GPS, modern ones with multi-network setup are pretty precise. Even google maps shows current speed. For my 16-year old BMW 3 its about 3-4 kmh below what it shows, regardless of actual speed. Never had a speed fine en Suisse.

Slow drivers cause other drivers to become impatient which ultimately causes accidents. I have no patience for slow drivers who have no need to reduce their speed.
