Lapped Cars

Lapped cars giving DRS is way too powerful, giving nearly a second of free speed without any drawback or skill, just getting lucky. This effect is amplified when the competitor has pit and you haven't, it completely negates the overcut and sometimes will even put you over a second back. This seems like a huge balance issue because it can mean the difference between race winners and championships, but it completely based on luck of where the lapped cars are. My propositions is to just get rid of their DRS giving ability.

Yup it will be great if lapped cars doesn’t trigger DRS. 

Or just add the blue flag
