There is car manufacturers and petrol heads lobby to not touch the unrestricted speed limits on the autobahn but there are also people who lobby for sensible speed limits as most people drive at about the speed a speed limit would be at anyway (120-130km/h) and the added energy used at speed along with dangerous situations coming from very high speed deltas are not good. A truck is always going to be 90-100 km/h and when a thrill seeker whizzes past them at 250 then the reaction time available and potential energy is killer.
