The plans of the Montreal students to disrupt the Grand Prix are being advertised on posters around the city. These call for the students to gather at the Berri Metro station, on the yellow line (the only Metro that serves the Grand Prix) at 10.30 in the morning on Sunday, with the instruction not to board trains until a signal is given.
The poster features an unpleasant image from CART from 2001 when Alex Zanardi lost his legs when hit by Alex Tagliani at the Lausitzring in Germany. The picture has no relevance to F1 at all, beyond being two racing cars and is designed simply to draw attention to the poster.
One can add accusations of ignorance and bad taste to whatever list one cares to create about the behaviour of the protesting students.
