Even if my study about driving was for the big men (showed that is actually useless) i think that is not very important for the guards too. Ive bought my SG
(2370199) for 4.2M x-France NT member and his driving is only 8. Yes driving is cheap, but what u pay what u get. I rate driving among with SB as the least useful skills of the game. Maybe this can change in the future but for now thats my opinion
