Daniil Kvyat needs to wake up to himself, it would seem he feels he has a right to be in F1 regardless of his deteriorating skill set, and blaming Sainz for the incident is just pathetic and childish.
Personally, I can't see him driving next season, if he remains it will be as test driver, and if RB/TR keep him on as a main driver there is something seriously wrong with the management of TR, Kvyat has cost himself and RB/TR a lot of unwanted time & money in car repairs, time & money that could of been spent on car improvements and honing valuable race craft, he doesn't want to, or can't accept he has screwed up on many occasions, and now has a long way to go to recover from the damage he has caused to his reputation, with this latest incident just making it easier for TR to bring Gasly on and relegate Kvyat to test driver for any remaining contract he may have.
I think Daniil's short career in F1 is drawing to a close very very quickly, which is sad, but he only has himself to blame.
