in an actual race car, you can only turn your head so much. your helmet is strapped to the neck brace, PLUS you have the bolsters of the seats that protrude so far out that you can't see anyway. speaking of helmets, those are another factor that limit your vision. Whenever I need to look around in GTS using group cars, I use the right stick (I know, im saving for a G29 lol) to look around and it's very limited (as it should be) but in a normal car, it works really well.
Yes, I've also seen shift lights, there are many different styles, some cars in game will flash the dash. We won't talk about the ones that come with those giant tach gauges people mount on their dash haha. as for split times being updated the way it does in game, I don't think I've seen that. the real time updates that tell your time distance from the car ahead/behind? I've seen lap times but that's about it.
sorry if this is getting off topic, apologies OP.
