He did chase him down, either that or was riding round in circles.He didn't chase him down, he caught up with him on the same journey, which underlines how stupid and pointless the dangerous overtake was.
I'm not sure how it all started - it didn't look like a close pass to me. The cyclist was too aggressive for his own good and will get stabbed one day. Nice outcome though.
5/ Samuel Barbers' Adagio for Strings(also Platoon)Music for the gif of the actual fall:
1/ Entrance of the Gladiators (you know, the circus music)
2/ Sad violins.
3/ Laural and Hardy theme tune
4/ Faure's requiem like off Platoon
