Blur is a Bizarre Creations game (creators of PGR, MSR and F1'97 in racing genre) published by Activision in 2010 and it's one of finest vehicular combat racing game ever made. Incredible car handling with much difference in each vehicle make it very hard to play for casuals and rewarding to hardcore gamers. I can describe online gameplay as CoD with cars but better and greater (luck = skill = experience).
Unfortunately soon after Blur release, Bizarre Creations was closed by nazists and fans for this brilliant racing game won't see sequel soon (if ever).
Sitting in a chair, doing some stuff, playing Blur when damn nazi comes to your room and fuck up your game by taking servers, putting lag and saying "no more Blur in future for you, you silly Polish shit" and gives new CoD instead.
