Being from Germany you probably know your countries statistics on the effect of speed alone on number of accidents:I did not want to elaborate on the speed, but it sends a shiver down my spine thinking of that driving style with wife and child on board...
In 2022, there were no more accidents per kilometer on sections without speed limits than on routes with speed limits of 120 or 130 km/h.
Unless you think Germanys highways are magical, even though they are older and way more crowded.
