Paddy Lowe has been allowed to join Mercedes on June 3rd, rather than next year as expected. He'll be their new Executive Director (technical) so he could make his first appearance for Mercedes at the Canadian GP.
I enjoyed the last race, especially because Alonso won in Barcelona. We do need to work on our qualifying and get Massa and Alonso up nearer the front of the grid, instead of them starting 5th & 6th or 5th & 9th like what happened at the Spanish GP. Also, since James Allison has left Lotus and has been linked with Ferrari, i'd like to see him sign with the team. Especially since he's worked with Alonso in the past at Renault.
And there's now an issue with tyres. Red Bull made a big fuss after the Spanish GP saying 4 stops was say too many (which I kinda agree with, especially because there were over 80 pit stops in total in Barcelona) but Lotus because they've mainly been doing 3 stops this year and they've worked out for them, they had a dig at Red Bull. And so did Ferrari from what I read. But Pirelli have said they'll change the tryes around for when Canada comes around so we should be then seeing 2 stops from teams.
