After being read into and tracking the details of every OIS in my state over the last decade, it is painfully obvious that this is a skill set that needs to be trained to.
Not just bailing out of cars or running "highspeed" drills. Simply a demonstration of things such as how rounds perform when striking an intermediate barrier. After a couple years of running vehicle based classes, we hear at least one LE or .mil guy upset that he had worked 5-10-15 years without this kind of training.
Over the past few years we have seen a number of cases of suspects using vehicles as a weapon against officers, going for guns while inside of cars, and one sheriff ambushed and killed in his car while eating lunch. Not one of the officers I spoke to after the shooter had any idea what was going to happen when his rounds impacted body panels or glass. The folks picking out ammo also do not tend to look at these topics and instead focus on limited penetration due to liability concerns of over penetration.
