I just want to say: GTA5 has both TPP and FPP. Driving a GTA5 car in TPP is ok, but driving it in FPP with PC keyboard on/off controls is pure hell.
The only real problem (albeit a pretty big one) that I noticed was that the characters eyes were way too low. It felt like controlling a midget behind the wheel which made observing the road and traffic cumbersome.
And as mentioned by sinister.sinner, riding a bike in FPP was pretty good and fluid.
