Throughout his career in GP3, Daniil Kvyat became known as "Danny Crash" because of the sheer number of times he wrecked either his car, or his and one or other competitor cars during races. It seems that habit hasn't gone away as this weekend he caused yet another crash in F1 - this time hitting Alonso and bouncing him into Verstappen, taking both out.
This is nothing new. Just off the top of my head, these are the crashes he's caused recently that I remember:
2015 Japan, Q1 - crashed and missed everyone
2016 Russia, Lap 1 - crashed into Vettel twice and Ricciardo once. This was when he was demoted.
2016 Austria, Q1 - crashed and missed everyone
2016 Monaco, Lap 21 - crashed into Magnussen.
2016 China, Lap 1 - crashed into Vettel, who was bounced into Raikkonen.
2016 Brazil, crashed into Palmer.
2016 Spain, crashed into Magnussen.
2017 Spain, pre-season testing.
2017 Monaco, crashed into Perez.
Kvyat is a dangerous F1 driver. Yes, all F1 drivers take risks but most of those are calculated risks and when there just isn't room, the other drivers tend to back off and try again. Not so for Danny Crash - he'll jam that car in where it just won't fit and his attitude is "me first, and screw everyone else".
At some point the FIA are going to have to step in and take away his F1 license because at the rate he's crashing into other cars right now, he's going to get someone killed.
