I learnt how much fun the new BMW M4 is to drive and I also learnt while having it that you need to be sensible and know how to handle a car with such a punch properly. Unfortunately for the 38-year-old who was test driving this M4 in Germany, things went very sour very quickly. The car left the slippery road and went down a 50 m long bank into some trees before coming to rest on its roof. The accident was a result of excessive speed and both driver and passenger had multiple traumas. An ambulance and helicopter arrived to transport the two to a hospital but their current condition is unknown. Be safe out there people and if you want to buy one of these M beasts, then please do an advanced driving course before hand. This can happen so quickly!
