> Modern cars, especially the slightly better class ones, make hardly or no sound and do the max speed (120-130km/h in EU depending on the country) without noticing it at all if you don't stare at the instruments.
The other thing I notice around here is that the roads are constantly getting better: wider, better lighting, better marking, curves get straightened out, foliage & trees on the side are cut to improve visibility, etcetra.
All this never seems to lead to an increase in speed limits.
So you can be on a curvy shady narrow road in the dark and rain. Max 100 kph, or 80 at winter. Wide road, good surface, good visibility, no traffic -- max 100 kph, or 80 at winter.
I can't bring myself to understand by which logic both of these speed limits can be right. One must be horribly unsafe, or the other must be horribly slow for the conditions.
Likewise, the danger posed by a bit of speeding is completely different on those segments..
