Safety as 2 big crashes back to back but it was more so to allow riders to get back on the bunch as so many riders were involved.
When they neutralised for the first minute and then let them go I think the organisers thought nobody would be harsh enough to attack off the front, and Sky did.... so they neutralised again and stopped.
No matter what they done there regards stopping/neutralising it would always appear to be a shambles as so many riders/cars and information aint exactly easy to get out! But think they have done a good and fair job here and back underway now.
