SPA-FRANCORCHAMPS, Belgium -- A look at the main talking points from the Belgian Grand Prix, where Sebastian Vettel claimed a third career victory at Spa to reduce Lewis Hamilton's lead at the top of the drivers' championship to 17 points and a reminder why the Halo safety device is on Formula One cars in 2018.
Vindication for the Halo: The incident at the start of the race looked eerily similar to the one which cost Fernando Alonso the 2012 world championship. This time, Alonso played the role of Romain Grosjean in the way his car flew violently over another, but he was powerless to stop the incident after being thumped from behind by Nico Hulkenberg.
