Lot of ill-judged replies here in my humble opinion, the poor bloke concerned is barely cold.
Let's just consider how many years driving experience this chap has probably had, the fact that railings wouldn't have made a great deal of difference looking at the state of the front of the car, and also anyone can have a heart attack, at any time, chances are the poor chap was dead before the car even hit the building. Having seen the speed of a heart attack and it's effects at first hand, I really think that's the most probable explanation, he could have been 25 or 105, makes no odds.
