Lewis Hamilton quipped that being benched in FP2 in Canada felt like being back at school, in the wake of the error that consigned him to the garage for the bulk of the session.
Hamilton led the way in the opening practice session at the Circuit Gilles Villeneuve on Friday but slid wide through Turn 8 in the second session and hit the wall.
Hamilton was able to recover his damaged W10 to the pit lane but Mercedes was forced to undertake repairs that meant he did not re-appear in the session, limiting his running to just eight laps.
“The morning session went smoothly; the track was very dirty in the beginning, but we're all in the same boat,” said Hamilton.
“I made a mistake in FP2 and damaged the car. The boys tried really hard to fix it, but there wasn't enough time. I don't remember the last time I missed a whole session before.
“It's definitely not great to watch the session from the garage; it feels like sitting in the headmaster's office, wishing to be back in class.
“It was an innocent mistake, I was doing multiple laps on the Medium tyre and was really trying to find the limit.
“Obviously I went slightly over, I had a big snap out of Turn 9 and was drifting for a long time, hoping I wouldn't hit the wall.
“But these things happen; you just have to put it behind straight away you and get back on the horse.”
Valtteri Bottas finished the day third overall, within two-tenths of a second of pacesetter Charles Leclerc.
“The car feels strong, but we have some work to do on the balance; the car became more difficult to drive with the changes we made for FP2, but it also felt a little quicker,” he said.
“So we need to review if there's anything we could have done better for FP2 and what we're going to do for tomorrow.
“It's nice to have a new engine with a bit more power; it's not a huge difference, but you can feel it, and it's a really good feeling.
“The car seemed strong on both long and short runs, but Ferrari was very quick on the straights, so I expect it to be a very close fight tomorrow.”
