20 cars were there, and 20 cars toook of on a a warmup lap.
14 cars then pulled into the pits, and only 6 cars to the start. The cars in the pits still had the option of starting from the pits, and as you may have noted, the drivers stayed in, the teams were ready to fuel the cars, and at least on the Danish signal, we heard the Renault to Alonso radio feed, where the team told Alonso:
"we are backing you in, they all acme to the pits"
So even though the teams had agreed, they were not quite sure, and I read that to mean, had McLaren taken the start then Renault would ahve gone out as well.
