So easy to bring a nation to its knees

In the wake of the present "artificial " oil crisis, thanks to fortune earning officials claiming a further pay hike, the image above brings some ironical smile to me and maybe to all those people running from pillar to post to gas station for a drop of fuel.
It happened today that I heard a man proclaiming proudly that he can live without his wife for a couple of days but wants fuel now, with his "better half" giving a healthy laughter behind. Made me think this.
Its alright that this fossil fuel is essential for us but a lack of it for a few days actually brings everything to complete halt is worrying. The officials at these PSUs came together and were actually able to hijack the nation and bring it down to knees. Being so much dependent on something is not a good sign considering the fact that our neighbours are not "friendly" by any sense of the word. I shall refrain from drawing any conclusions for this may seem a mountain out of mole hill to many.
And for the closing words, while I was discussing this current situation and the stern stand of PSU officials, we realised that the Armymen and Policemen receive a paltry salary when compared but never go on strike demanding a pay hike.
What if they decide to make such demands???

SAVE THE FUEL!!!

This is a bit of Maths. Lets ring some disappointments to all those greenheads who think that bicycling to work daily will save this earth.

Case in point : Formula 1

Average fuel consumption by one car on raceday : 200 litres
Number of cars running the full race : 16
Total fuel consumed on raceday : 3200 litres
Total fuel consumed over complete race weekend : 4000 litres ( being too optimistic)

Case in point : Average 2 wheeled commuter

Daily distance traveled : 20 Km
Distance traveled in a month : 25 x 20 = 500 Km
Mileage returned by humble 2 wheeler : 50 Kmpl
Fuel consumption in a month : 10 litres
Annual fuel consumption : 12 x 10 = 120 litres
4000 litres consumed in : 33.33 years

Conclusion : The fuel an average commuter would burn in 33 years is smoked up over a weekend by a bunch of motoring enthusiasts cheered up by millions of fans.
Now go ahead and sweat it out for a day on bicycle and proclaim that you saved your dear earth!!!

Nissan GT-R

This car is amazing. The Nissan GT-R. And the USP of this car is that it laps the Nurburgring Nordschliefe in 7 minutes 32 seconds. This is 3 seconds faster than the Porsche 911. Good. But what's the point?? Will anyone go out and buy a car that does a fast lap on some track; whose name isn't that easy to spell? Fact is; YES they will. 'Cause the track is mother of all tracks and every manufacturer tunes its car to go faster than others around here.
The icing is that GT-R is about half the price of 911. Now which set of wheels would you choose? Decisions decisions.......

The new Mercedes E-class 2010

So here it is. The new Mercedes E-class slated for 2010 launch. And what does it look like??? To me, a bit like CLS. And my personal feelings?? You see, E-class is a step above the entry level and this feels to outspoken for that. I would prefer the current E-class. Thank you please.
