my vacation this year was 1500 km one way, at least 80% of which was done at 130km/h or more (both ways). i was one of very many doing a trip of this length judging by license plates at the destination.
So you were exceeding the speed limit almost all the way? My journey was a similar distance and only the German stretch had any roads with speed limit higher than 130 km/h. Perhaps next time I do it I should record the speed as I go. The average speed was probably about 60 km/h so the amount of driving above 130 must have been quite small, some of it was a lot faster than that though, just for fun on the autobahn.
And of course the vast bulk of traffic on the roads is very much slower. Also quite a lot of ICE cars are not built for sustained driving at high speeds anyway.
