Ok, I've been thinking and there's a few things that'd be easy for PD to implement and would make GTS more enjoyable for me. Ok so firstly, the racing line, I'd love to be able to make my own, only on hotlapping (time trial) because there's times where you can get away with accelerating when the games telling you to brake, well you get the idea.

It may seem super trivial to some of the racing sim purists, but I think the soundtrack is absolutely terrible. Remember GT4? Van Halen, Papa Roach, Jeff Beck, James Brown? That was music to drive to, and gave an already awesome sim that extra something. The GTS soundtrack sounds like Kenny G played over a drum track.
Bring back Trial Mountain and Grand Valley Speedway.
Simplify the main menu interface navigation. It seems too easy to get lost in the weeds of the sub-menus.
Buying stuff with mileage points? Is this a racing sim or Delta's frequent flyer program? Race cars, win money, use money to buy things.
Need more vintage race cars, not a bunch of "GT Vision" concepts that all look like a Lambo in a trash compactor.
