Most turns most of a time, including 90dg ones in junctions are "rounded". Public roads are made for very various type of vehicles, including long wheel base. I really find it hardly to be an issue, that in some rare times/turns i need to relocate hand once or twice. Suggesting to watch some videos how to relocate hands quickly without loosing control and without loosing knowing of wheels current position and centerline. LOL, if nothing else, how animated hands in asetto corsa in-cabin videos move
. Of course, old-school "shuffling" method is not of such, too slow. Lorry driving one-hand with palm steer is quick but lack of control/secure hold, better used only for parking. Modding car to be able to turn each and every turn without hand relocation like in some initial-d gum tape deathmatch seems a bit artificially thought out issue, not worth wasting time/money "fixing".
