VSC

When a VSC is deployed then everyone should be slowed down to the same speed. I just lost 1 second in a single sector because the guy in front of me had lapped a car and I hadn’t. Ruined any chances of a good finish for me. If this aspect isn’t changed to improve then I will give up on the game. You solved the lag issue but replaced it with another issue.

In real racing some cars cars do gain and others lose out when a VSC comes to an end, it depends where you are on a track, braking, exiting a corner or on a straight. 

When a real SC comes out though it bunches everyone up

Well, the purpose of a VSC is to maintain the gaps that would be lost from the deployment of a SC.  How well a VSC does this is based on the speed of the VSC and the maximum speed of the slowest corner(s) on a track.  In some scenarios, some cars will benefit and some will be hindered.
