To be frank, all drivers in at least the top three team plus Mclaren drivers obviously would easily win the driver championship with the Mercedes W07 car. Mercedes the car manufacturers do not need to use underhand tactics to have someone else other than Hamilton win the championship. However, such a statement does not exclude persons operating within the Mercedes F1 circle with their own personal agenda from attempting to bring about this outcome.
The problem with the current situation with Hamilton is, there is a pattern here that goes back to 2014. Hence it sort of makes it abit hard to accept the conclusion that it is just simply bad luck. In a pool of the same equipment, you would expect this sort of thing to have a random pattern across the equipments in the pool. When you begin to see concentration of anomaly mainly on one particular member in the pool, then statistically you would begin to think that it is not random enough for the incident to be classed as bad luck. It more plausibly begins to look like deterministic factors bringing about the concentration of the defect on the single equipment.
The Hamilton situation is an embarrassment for Mercedes, as their engine is blowing up on the car of the driver with the most international media appeal. Every media channel would have pictures, videos and commentary of the Mercedes engine blowing up and a string of engine problem bedogging the current world champion. Hence, it is real bad news for Mercedes whichever way you look at it.
That does not eliminate the fact that there may be something amis going on inside the Mercedes camp for reasons that does not take into consideration the effect on the Mercedes brand. The Mercedes F1 team may attempt to explain these incidents as bad luck, but they are increasing becoming quite unbelievable. Hence the pressure is on the team to find out what is amis and fix it. Because the next failure, which l feel is very likely to occur before the end of the season, would most likely be very damaging in a number of ways.
For a start many would have on the back of their mind that Mercedes have fixed the 2016 driver world championship outcome. This would not be good for Rosberg, as he would not get the respect that he deserves for winning the 2016 championship if he manages to pull it off. There always would be talk of Mercedes dodgy dealings that assisted him in beating Hamilton. Both of these things may not be the case, but people would think it.
