Just give my 2cents after reading the two articles about it
1. He shouldn't have busted the u turn before the check point
2. Whether or not he was intoxicated , never drive drunk !
3. The police had no reason to pursue unless when u turned he did so erratically
Which neither article says the driver did

In my personal opinion I don't think he was "drunk" , but definitely had a beer or two , after seeing the cops following him adrenaline and alcohol doing there thing leading to bad decisions and over driving the car , not saying the xf can't handle 140 which i believe it can but only in a straight line , this is no f1 car or a super car it can't handle sudden movements @140 mph (which i believe must be an exaggeration on how fast the driver was going)
Especially on stock wheels and suspension
Hell I nearly spun out doing 50 merging onto the highway through a sharp corner although it was a wet road but that's not the point ,
May this guy rip and another xf bit the dust
If your intoxicated take the dwi ticket , paying a fine and losing your license for a few months is better then losing your life
