(no setup + no strategy) should be DNS.

slow robots backmarkers are making all us mad! hahaha

same.My rivals always get DRS from none-active backmarkers.

Yep I agree, no point of letting someone who can't be bothered to play the game get points. Even if they log in every day the default start is so slow and creates unnecessary traffic.
Especially sucks if you get beaten by a person who doesn't set up even if you put the effort in.
Although I don't think any change like this will ever happen soon considering backmarker DRS and auto kers still exists...

Auto Boost is faster than manual boost
25% each stint in a 3 stop strategy
33% each stint in a 2stop
50% each stint in a 1 stopper

That means that you drive faster when you don't watch the race?

Debatable

If you know the tyres and push level for the temp then you will do well if you are unlucky and cook the tyre then you will be slightly slower

¿? are you faster on clean air or when overtaking?

I'm agree, because the inactive backmarkers are a pain in the ass (sorry for the expression); for things that are their fault (by being slow) who has lost places or a podium for their obstruction?

It's easy competition but annoying.
