A few thouguts
I would like to see the possibility of a mechanical failure or crash if you do poorly on a mini game. Maybe lose a tire after a pit stop if you have a bad stop.
Also would like to see more various weather. Im at season 5 and have not used wet tires yet.
At the end of the race if you have less than 1 liter of fuel remaining you are given a penalty. F1 has the rule where you must have 1 liter of fuel remaining for testing. Also if you run out of fuel a 10 place starting penalty for the next race.
Finally a few new mini games would be nice. Maybe have traffic with the hairpin & chicane challanges. Love the idea of a previous post to have a reverse back marker challenge to stay clear of the leaders.
There are now variable punctures in v1.3, and also variable weather, and wet weather!
Some great ideas there - I'll look into them.
