Something to tax your memories and knowledge on.
Di Grassi's incident today is something we've not seen in F1 in a while. When was the last time a driver failed to take the start because they spun/crashed on a warm up lap or going to the grid. I remember Blundell doing it in the 95 Canadian Grand Prix and Coulthard doing it the same year in Italy. But both were able to take the start. (Coulthard was particularly luck that a first lap crash caused a restart and allowed him to re-take his pole position).
Didn't something happen to Schumacher on the way to the grid in the 05 Chinese Grand Prix?
Prost in San Marino in 91 is another one on the warm up lap. These are high-profile names i'm mentioning here. Di Grassi is in good company!
Who else has it happened to?
