Piers was saying if it had happened further from the start it might have been a different story...
It is very fortunate it was on the first lap, and early in the lap, as that's why the medical car was close behind him.
They were also discussing the halo and how unpopular they were at the beginning.
The halo is always going to be controversial I think. In this crash it's done a good job, however there are crashes in which it would have caused problems.
Nico Hulkenberg had an issue wriggling out of his car when it was on fire and upside down because the halo impeeded his way. The time in which drivers have to be able to jump clear of the car was increased from 10 to 15 seconds because of the halo so in a fire it can cause issues. A lot of drivers feel it can cause problems in more incidents than in which it will help.
