Any racing game ever - Forza Horizon and Forza 4 have shown me that you're not playing a racing game unless you're driving manual with clutch. It also showed me that any racing game without the clutch option is for pussies (in other words, having to actually shift, not just "hold R until you win and press rthumb to shift")
Damn straight- I remember doing the EZ5plus review and one of the latest games was Die wilden Hühner und die Jagd nach dem Rubinherz/The Wild Chicks and the Hunt for the Ruby Heart (a German franchise aimed at younger girls) and it had a driving section with proper touch screen gears and more on it. Bastard hard that one.
Trouble for you though will probably be that sports cars seem to be shifting towards autoclutch/semiauto and flappy paddle gearboxes without a real clutch.
Being slightly more serious though I did abuse gears when playing the need for speed games- as it seemed to handle going from 5th or 6th to first at 200KPH I used it as it braked better than the actual brakes, especially in the 90 degree corners at the end of straights that most of the games seemed to enjoy throwing at you in the later levels.
