#3 Stroll & Hartley (Canada)
The fast and tight straights of Canada's Circuit Gilles Villeneuve usually produce high-speed crashes and we saw another in 2018.
Going into the second chicane on the first lap, Brendon Hartley was hanging around the outside of Lance Stroll in the hope of overtaking the home favourite, but this would go drastically wrong.
Stroll - perhaps from defending too vigorously - slipped mid-corner, forcing Hartley into a wedge too small to fit his Toro Rosso car and also the outer wall.
The Kiwi's left side was destroyed and his car rode up on Stroll's racer, sending them both into the crash barriers and out of the race. Who was at fault is difficult to say and the FIA understandably took this stance too, choosing to punish neither of the pair for the incident.
