Will some of these features be added to the game at some point?

I was wondering if the devs had some of these features in mind:
Rain/Snow + Slippery Terrain when raining and Windshield wipers!
Cold Start / Starting Battery Voltage?
Racing
Leaking fluids
seized engine
Temperatures affect car w/ gauge
Better gas simulation
Derby
Opening Doors / Hood / Trunk / etc
Thanks!
